Currently we have a bit of a mess related to tids:
- sanitizers re-declare kInvalidTid multiple times
- some call it kUnknownTid
- implicit assumptions that main tid is 0
- asan/memprof claim their tids need to fit into 24 bits,
but this does not seem to be true anymore
- inconsistent use of u32/int to store tids
Introduce kInvalidTid/kMainTid in sanitizer_common
and use them consistently.

InternalScopedString uses InternalMmapVector internally
so it can be resized dynamically as needed.

Right now, when you have an invalid memory address, asan would just crash and does not offer much useful info.
This patch attempted to give a bit more detail on the access.
