Update TSAN suppressions.

Update TSAN suppressions.

TSAN suppressions need to be on their own line, even free of comments.

Also, temporarily add SK_ANNOTATE_UNPROTECTED_READ to sk_acquire_load.
Will remove this when we're done iterating on SkBarriers_tsan.h: TSAN
has an atomic load that makes the annotation moot.
