bootstrap: Don't override `debuginfo-level = 1` to mean `line-tables-only`

This has real differences in the effective debuginfo: in particular, it omits the module-level information and makes perf less useful (it can't distinguish "self" from "child" time anymore).

Allow passing `line-tables-only` directly in config.toml instead.

See https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/debuginfo.20in.20try.20builds/near/365090631 and https://rust-lang.zulipchat.com/#narrow/stream/238009-t-compiler.2Fmeetings/topic/.5Bsteering.5D.202023-06-09/near/364883519 for more discussion.

rustdoc: search for slices and arrays by type with `[]`

This feature extends rustdoc to support the syntax that most users will naturally attempt to use to search for slices and arrays. Part of #60485

Function signature searches already support arrays and slices. The explicit name `primitive:slice<u8>` and `primitive:array<u8>` can be used to match a slice or array of bytes, while square brackets `[u8]` will match either one. Empty square brackets, `[]`, will match any slice regardless of what it contains.

Preview:

* [`option -> []`](https://notriddle.com/rustdoc-demo-html-3/search-slice-array/std/index.html?search=option%20-%3E%20%5B%5D)
* [`[u8] -> str`](https://notriddle.com/rustdoc-demo-html-3/search-slice-array/std/index.html?search=%5Bu8%5D%20-%3E%20str)
* [`Box<[u8]> -> str`](https://notriddle.com/rustdoc-demo-html-3/search-slice-array/std/index.html?search=Box%3C%5Bu8%5D%3E%20-%3E%20str)

Motivation:

When type-based search was first landed, it was directly described as "incomplete". Here's [a comment] from the discussion thread:

[a comment]: https://github.com/rust-lang/rust/pull/23289#issuecomment-79437386

> This is looking really great, nice work! I can think of a number of cases that aren't quite covered by this, but I feel like this is a great improvement regardless and it can always be iterated on so I'm fine landing with a few known cases where it may not work :)

Filling out the missing functionality is going to mean adding support for more of Rust's [type expression] syntax, such as slices (in this PR), tuples, references, raw pointers, function pointers, and generics.

[type expression]: https://doc.rust-lang.org/reference/types.html#type-expressions

There does seem to be demand for this sort of thing, such as [this Discord message](https://discord.com/channels/442252698964721669/443150878111694848/1042145740065099796) expressing regret at rustdoc not supporting tuples in search queries.

rustdoc: Add `item_template` macro

This change removes the use of `self.borrows()` in Askama templates, removes code duplication from `item_and_mut_cx()`, and improved readability by eliminating the prefix `item_template_` when calling from the template.

Static loading `ntdll` functions does not work for UWP programs, which will end up link errors complaining about missing symbols, or failure to pass the WACK tests. The breakage was introduced in #108262.

This PR basically reverts part of the changes in #108262 for UWP only, and fixes some lint suggestions.

Don't compile rustc to self-test compiletest

This was changed from stage 0 to 1 in https://github.com/rust-lang/rust/pull/108905, but I'm not sure why. Change it to `top_stage` instead to allow people to choose the stage.

This should save quite a bit of time in the `mingw-check` builder, which explicitly runs `x test --stage 0 compiletest`.

Note that this also fixes a latent bug that depended on running `x build compiler` before `x doc compiler`, as well as a couple cleanups related to symlinks (which made the latent bug easier to find).

rustdoc: re-elide cross-crate default trait-object lifetime bounds

Hide trait-object lifetime bounds (re-exported from an external crate) if they coincide with [their default](https://doc.rust-lang.org/reference/lifetime-elision.html#default-trait-object-lifetimes).
Partially addresses #44306. Follow-up to #103885. [Zulip discussion](https://rust-lang.zulipchat.com/#narrow/stream/266220-rustdoc/topic/clean_middle_ty.3A.20I.20need.20to.20add.20a.20parameter/near/307143097).

Most notably, if `std` exported something from `core` containing a type like `Box<dyn Fn()>`, then it would now be rendered as `Box<dyn Fn(), Global>` instead of `Box<dyn Fn() + 'static, Global>` (hiding `+ 'static` as it is the default in this case). Showing `Global` here is a separate issue, #80379, which is on my agenda.

Note that I am not really fond of the fact that I had to add a parameter to such a widely used function (30+ call sites) to address such a niche bug.

Add deprecation warning to python versions <3.6 in x.py

Introduced based on conversation on Zulip. This is a repeat of #110439 with two changes:

- Warning rather than exit
- Can be suppressed via an environment variable

The min to not get the warning is set to 3.6 because that's a fairly recent "old" version (went EOL in 2021) and it's the first version to support useful modern features like f-strings and type hints.

Rollup merge of #112413 - jieyouxu:fix-hidden-glob-reexports-span-order, r=petrochenkov
Adjust span labels for `HIDDEN_GLOB_REEXPORTS`

Addresses https://github.com/rust-lang/rust/pull/111378#issuecomment-1581226063.

### Before This PR

The possibility that the private item comes before the glob re-export was not account for, causing the span label messages to say "but private item here shadows it" before "the name `Foo` in the type namespace is supposed to be publicly re-exported here".

### After This PR

```rust
warning: private item shadows public glob re-export
  --> $DIR/hidden_glob_reexports.rs:9:5
   |
LL |     struct Foo;
   |     ^^^^^^^^^^^ the private item here shadows the name `Foo` in the type namespace
...
LL |     pub use self::inner::*;
   |             -------------- but it is supposed to be publicly re-exported here
   |
   = note: `#[warn(hidden_glob_reexports)]` on by default

Rollup merge of #112298 - est31:update_field_offset, r=Mark-Simulacrum
Update field-offset and enable unstable_offset_of

This makes the compiler use the builtin `offset_of!()` macro, through the wrappers in memoffset and then in field-offset.

Rollup merge of #112297 - jyn514:remove-exclude-kind, r=Mark-Simulacrum
bootstrap: Disallow `--exclude test::std`

Use the top-level Kind to determine whether Steps are excluded.

Previously, this would use the `Kind` passed to `--exclude` (and not do any filtering at all if no kind was passed).
That meant that `x test linkchecker --exclude std` would fail - you had to explicitly say `--exclude test::std`.

Change bootstrap to use the top-level Kind instead, which does the right thing automatically.
Note that this breaks things like `x test --exclude doc::std`, but I'm not sure why you'd ever want to do that.

There's a lot of churn here, but the 1-line change in the first commit is the actual behavior change, the rest is just cleanup.

Fixes https://github.com/rust-lang/rust/issues/103201. Note that this effectively reverts most of https://github.com/rust-lang/rust/pull/91965.
