Move -Wno-error=format from noOverrideGlobalCflags to
commonGlobalCflags so that projects can re-enable it with
"-Werror=format"

There was infrastructure to export ninja variables to bazel. Now that
the bazel migration is cancelled, we don't need it anymore.

Some clang unused-* warnings are not covered by "-Wno-unused". Add them
explicitly to avoid noise from these warnings, given that they don't
generally get fixed.
Test: Local clean builds.

No-one ever fixes unused-* or deprecated-* warnings in external/ (nor should they!).
-Wno-deprecated-enum-enum-conversion should probably have been added
next to -Wno-deprecated-anon-enum-enum-conversion when it was added,
since it's a major spam contributor, and equally unlikely that anyone
will clean them up.
-Wno-deprecated-dynamic-exception-spec is a weird special case because
it should be irrelevant after our next libc++ update, but in the
meantime -- because libc++ is used everywhere -- this is a massive spam
contributor that no-one on Android cares about because we don't use
exceptions (and the people seeing this can't fix libc++ anyway).

it gets a unique object per context.

The MLGO model we embed in the Android Clang is trained on ARM64
ThinLTO artefacts. Applying the model across architectures does not
necessarily translate to performance improvement. Therefore only enable
the optimisation on ARM64 ThinLTO for now.

This warning is triggered even when initializers don't have any
side effects, so it very rarely surfaces actual bugs/mistakes.
99% of the time it complains about a purely cosmetic issue.
Disable it by default in commonGlobalCFlags, which still allows
individual modules to opt into it.

We can save a significant amount of disk space by compressing
debug info in `lld` cc builds. This change configures a build
flag to instruct lld to compress debug info when building cc
libraries. Rather than adding a global config we add this to
each target individually to avoid linker failures on windows
cross build targets.

This enables Machine Learning Guided Optimizations (MLGO) for register
allocation. App launch performance on oriole-userdebug is improved by
0.53%, and binary size is very slightly reduced (e.g. 64 bytes for
libart.so).
