Auto merge of #110221 - jyn514:smaller-debuginfo, r=Mark-Simulacrum

Greatly decrease the size of `rustc_driver.so` when debuginfo is enabled

- Don't include extra unnecessary debuginfo when only debuginfo-level=1 is set
- Compress debuginfo sections to reduce the size of debuginfo on disk.

before: 650 MB
line tables only: 335 MB
compressed only: 216 MB
compressed and line tables: 186 MB
no debuginfo at all: 130 MB

Here's an example backtrace:

<details><summary>with `debuginfo=1` (what we emit currently for `debuginfo-level-rustc = 1`)</summary>

I want to investigate why `-C line-tables-only` is still ~tripling the size of the binary (update: done https://github.com/rust-lang/rust/pull/110221#issuecomment-1507563024), but this seems like a good improvement in the meantime.

I've tested that both valgrind and perf can read the debuginfo:

To test this, you can run `x build --stage 0 cargo`, set `build.cargo = "build/host/stage0-tools-bin/cargo"`, and then `x build --stage 2 std`. You should be able to compare the rustc_driver.so outputs to each other:
```
; ls -lh build/host/stage{0,1,2}/lib/librustc_driver*.so
-rw-r--r-- 1 jyn jyn 130M Mar  6 15:24 build/host/stage0/lib/librustc_driver-f265b505c593f632.so
-rwxrwxr-x 3 jyn jyn 216M Apr 11 00:51 build/host/stage1/lib/librustc_driver-3aa1aa8c8214a2de.so
-rwxrwxr-x 4 jyn jyn 186M Apr 11 00:54 build/host/stage2/lib/librustc_driver-02d96489c468b21e.so
```

The difference between stage1 and stage2 is `debuginfo=1` vs `debuginfo=line-tables-only`. Both stages have `-gz` (compressed debuginfo) enabled.

This depends on https://github.com/rust-lang/cargo/pull/11958 (and the exact commit of the cargo submodule will need to change before merging).

Helps with https://github.com/rust-lang/rust/pull/104968.
