[nsan] Emit calls to optimized functions (#98900)
As previously noted in nsan.cpp we can implement
optimized variants of `__nsan_copy_values` and
`__nsan_set_value_unknown` if a memory operation
size is known.
Now the instrumentation creates calls to optimized functions if there is
4, 8 or 16-byte memory operation like
`memset(X, value, 4/8/16)` or `memcpy(dst, src, 4/8/16)`
nsan.cpp provides definitions of the optimized functions.
