misc: improve clangd compile_flags.txt flags

This patch improves the compile_flags.txt config used to power clangd
for the rts C codebase. The flags in the file are sampled & deduped
from a real stage1 build with clang-19 and vastly improves the IDE
accuracy when hacking the rts.

For maximum code coverage under the default settings,
compile_flags.txt defaults to threaded+profiled+dynamic+debug way.
This does not mean profdyn needs to be actually built in _build/stage1
for IDE to work. To activate IDE for other RTS ways, simply remove one
of the -D flags at the end of compile_flags.txt and restart clangd.

testsuite: Don't consider untracked files in dirtiness check

Considering trees containing untracked files as dirty is a bridge too
far. The chance of an untracked file significantly affecting measured
performanced metrics is quite small whereas not collecting measurements
is quite inconvenient for some workflows. We now ignore untracked files
in the dirtiness check.

Fixes #25471.

rts: Allow use of GNU-stack notes on FreeBSD

Previously we gated use of GNU-style non-executable stack notes to only
apply on Linux. However, these are also supported by FreeBSD, which also
uses ELF. Fix this.

Fixes #25475.

rts: Fix EINTR check in timerfd ticker

When `poll` failed we previously checked that `errno == -EINTR` to
silence the failure warning. However, this is wrong as `errno` values
are generally not negated error codes (in contrast to many system call
results, which is likely what the original author had in mind).

Fixes #25477.

rts/RtsFlags: Refactor size parsing

This makes a number of improvements mentioned in #20201:

Introduce GHC.Tc.Plugin.lookupTHName

This makes it significantly more convenient (and less
GHC-version-dependent) to resolve a template-haskell name into a GHC
Name.

As proposed in #24741.

X86 NCG: allow VXOR at scalar floating-point types

The NCG can emit VXOR instructions at scalar floating-point types,
but the pretty-printer would panic instead of emitting the appropriate
VXORPS/VXORPD instructions. This patch rectifies that oversight.

Fixes #25455

rts: Fix platform-dependent pointer casts

Previously we had unnecessary (and incorrect) platform-dependent casts
to turn `OSThreadIds`s into a integer. We now just uniformly cast first
to a `uintptr_t` (which is always safe, regardless of whether
`OSThreadId` is a pointer), and then cast to the desired integral type.

This fixes a warning on musl platforms.
