[roll] Roll fuchsia [roll] Roll llvm-project/libc [libc] Disable -march=native in CI to fix sccache poisoning (#196560)

-march=native is incompatible with shared build caches because sccache
treats it as a literal string. Object files compiled on one CPU model
get silently served to runners with a different CPU, causing SIGILL
crashes in the opt_host memory tests.

Made LIBC_COMPILE_OPTIONS_NATIVE a CMake cache variable so CI can
override it. Both overlay and fullbuild workflows now pass
-DLIBC_COMPILE_OPTIONS_NATIVE="" to disable -march=native. Local
developer builds are unaffected and still default to -march=native.

Reverted the per-CPU cache key approach from #196477 in favour of this
fix, which addresses the root cause.

Bumped sccache key versions (v2) in both workflows to invalidate the
poisoned caches.
