[Patch AArch64] Add __ARM_FEATURE_ATOMICS
This keeps coming up repeatedly and the ACLE has finally added
__ARM_FEATURE_ATOMICS for the LSE feature in GCC. This is now part of
the latest ACLE release
(https://developer.arm.com/docs/101028/latest/5-feature-test-macros)
I know it's late for GCC-9 but this is a simple macro which need not
wait for another year.
Ok for trunk and to backport to all release branches ?
Tested with a simple build and a smoke test.
