  [tsan][go]: add a128 store, load, compare_exchange (#196833)

This commit adds a128 load, store and compare_exchange to the Go
sanitizer functions. This is needed for a new Go atomic type that
operate on 16-byte values.

The SANITIZER_GO macro was gating a128 and is now lifted. Based on the
__TSAN_HAS_INT128 macro definition, the only architecture excluded by it
that intersects with [Go race support
](https://go.dev/doc/articles/race_detector#Requirements) is s390x.
