Jonathan Swinney 07ff596404 runtime/internal/atomic: add LSE atomics instructions to arm64
As a follow up to an earlier change[1] to add ARMv8+LSE instructions in
the compiler generated atomic intrinsics, make the same change in the
runtime library. Since not all ARMv8 systems support LSE instructions,
they are protected by a feature-flag branch.
