Rust 1.74.0 introduced (unstable) support for the
`-Zdebuginfo-compression` flag, thus use it.
Note that the releases built by the Rust project (i.e. the ones provided
by rustup) do not enable support for zstd in their bundled LLVM (yet,
at least), thus the Rust compiler will warn, but the build will proceed:
warning: unknown debuginfo compression algorithm zstd - will fall
back to uncompressed debuginfo

Makefile.debug: support for -gz=zstd
Make DEBUG_INFO_COMPRESSED a choice; DEBUG_INFO_COMPRESSED_NONE is the
default, DEBUG_INFO_COMPRESSED_ZLIB uses zlib,
DEBUG_INFO_COMPRESSED_ZSTD uses zstd.
This renames the existing KConfig option DEBUG_INFO_COMPRESSED to
DEBUG_INFO_COMPRESSED_ZLIB so users upgrading may need to reset the new
Kconfigs.
Some quick N=1 measurements with du, /usr/bin/time -v, and bloaty:
clang-16, x86_64 defconfig plus

That's only a 3.11% overall binary size savings over zlib, but at no
performance regression.

Makefile.debug: re-enable debug info for .S files
Alexey reported that the fraction of unknown filename instances in
kallsyms grew from ~0.3% to ~10% recently; Bill and Greg tracked it down
to assembler defined symbols, which regressed as a result of:
commit b8a9092330da ("Kbuild: do not emit debug info for assembly with LLVM_IAS=1")
In that commit, I allude to restoring debug info for assembler defined
symbols in a follow up patch, but it seems I forgot to do so in
commit a66049e2cf0e ("Kbuild: make DWARF version a choice")

Makefile.debug: set -g unconditional on CONFIG_DEBUG_INFO_SPLIT
Dmitrii, Fangrui, and Mashahiro note:
Before GCC 11 and Clang 12 -gsplit-dwarf implicitly uses -g2.
Fix CONFIG_DEBUG_INFO_SPLIT for gcc-11+ & clang-12+ which now need -g
specified in order for -gsplit-dwarf to work at all.
-gsplit-dwarf has been mutually exclusive with -g since support for
CONFIG_DEBUG_INFO_SPLIT was introduced in
commit 866ced950bcd ("kbuild: Support split debug info v4")
I don't think it ever needed to be.
