rustdoc: Fix invalid handling of nested items with `--document-private-items`
Fixes#110422.
The problem is that only impl block and re-exported `macro_rules!` items are "visible" as nested items. This PR adds the missing checks to handle this correctly.

Avoid including dry run steps in the build metrics
Including steps executed during the dry run will result in a duplication of all the steps in the build metrics, which just adds noise.
Don't use `serde_json` to serialize a simple JSON object
This avoids `rustc_data_structures` depending on `serde_json` which allows it to be compiled much earlier, unlocking most of rustc.
This used to not matter, but after #110407 we're not blocked on fluent anymore, which means that it's now a blocking edge.
This saves a few more seconds.

Add list of supported disambiguators and suffixes for intra-doc links in the rustdoc book
This information is otherwise only provided in case an error occurs, which isn't great.

Set commit information environment variables when building tools
This fixes#107094.
~I'm trying to add a regression test for this issue.~
**Update**: I've added a test and a new test header `needs-git-hash` which makes sure it doesn't run when commit hashes are ignored (`bootstrap`'s `ignore-git` option).
Tagged pointers, now with strict provenance!
This is a big refactor of tagged pointers in rustc, with three main goals:
1. Porting the code to the strict provenance
2. Cleanup the code
3. Document the code (and safety invariants) better
This PR has grown quite a bit (almost a complete rewrite at this point...), so I'm not sure what's the best way to review this, but reviewing commit-by-commit should be fine.

Bypass the varint path when encoding InitMask
The data in a `InitMask` is stored as `u64` but it is a large bitmask (not numbers) so varint encoding doesn't make sense.
tests: adapt for LLVM change 5b386b864c7619897c51a1da97d78f1cf6f3eff6
The above-mentioned change modified the output of thread-local.rs by changing some variable names. Rather than assume things get put in %0, we capture the variable so the test passes in both the old and new version.
Check freeze with right param-env in `deduced_param_attrs`
We're checking if a trait (`Freeze`) holds in a polymorphic function, but not using that function's own (reveal-all) param-env. This causes us to try to eagerly normalize a specializable projection type that has no default value, which causes an ICE.
Fixes#110171
Various minor Idx-related tweaks
Nothing particularly exciting here, but a couple of things I noticed as I was looking for more index conversions to simplify.

Correct default value for default-linker-libraries
This setting is false by default according to rustc code here: https://github.com/rust-lang/rust/blob/master/compiler/rustc_session/src/options.rs#L1236
I tested on a project and confirmed the behavior described. First, with no value, the `-nodefaultlibs` linker flag is present. Setting this to false has no effect, as well. The linker flag still appears. Setting it to true removes the linker flag as expected.

Remove some suspicious cast truncations
These truncations were added a long time ago, and as best I can tell without a perf justification. And with rust-lang/rust#110410 it has become perf-neutral to not truncate anymore. We worked hard for all these bits, let's use them.

Spelling librustdoc
This is split from https://github.com/rust-lang/rust/pull/110392
There's one change to src/tools/rustdoc-gui/tester.js which feels like a reasonable thing to piggy-back here.
rustdoc: stop passing a title to `replaceState` second argument
As described on [MDN's replaceState page], this parameter is not currently used, and the empty string is "safe against future changes to the method."

Alloc `hir::Lit` in an arena to remove the destructor from `Expr`
This allows allocating `Expr`s into a dropless arena, which is useful for using length prefixed thing slices in HIR, since these can only be allocated in the dropless arena and not in a typed arena.
Permit MIR inlining without #[inline]
I noticed that there are at least a handful of portable-simd functions that have no `#[inline]` but compile to an assign + return.
I locally benchmarked inlining thresholds between 0 and 50 in increments of 5, and 50 seems to be the best. Interesting. That didn't include check builds though, ~maybe perf will have something to say about that~.
Perf has little useful to say about this. We generally regress all the check builds, as best as I can tell, due to a number of small codegen changes in a particular hot function in the compiler. Probably this is because we've nudged the inlining outcomes all over, and uses of `#[inline(always)]`/`#[inline(never)]` might need to be adjusted.

### What does this PR try to resolve?
Making cargo a workspace.
Why doing this?
* `rustc-workspace-hack` is primarily for sharing dependencies between rls and cargo, as rls previously depends on cargo. After rls retired, it is no longer the case sharing dependencies.
* It's q bit painful that cargo needs to deal with some dependency and licensing complexities. For example, #108665 failed because of the interaction bewteen `windows-sys` and `raw-dylib`. It currenctly blocks cargo's feature `-Zgitxodie` from moving forward.
* See rust-lang/cargo#11851
### Benchmark result
I've done a simple benchmark on both keeping or removing entire `rustc-workspace-hack`. It had no significant difference. Both took ~2m30s to finish `./x.py build -j8 src/tools/cargo src/tools/rls src/tools/clippy src/tools/miri src/tools/rustfmt`. Environment info:
```
host: aarch64-apple-darwin
os: Mac OS 13.2.1 [64-bit]
```
A sophisticated benchmark may be needed.
