lsan: remove pthread_detach/join interceptors
They don't seem to do anything useful in lsan.
They are needed only if a tools needs to execute
some custom logic during detach/join, or if it uses
thread registry quarantine. Lsan does none of this.
And if a tool cares then it would also need to intercept
pthread_tryjoin_np and pthread_timedjoin_np, otherwise
it will mess thread states.
Fwiw, asan does not intercept these functions either.

sanitizer_common: add simpler ThreadRegistry ctor
Currently ThreadRegistry is overcomplicated because of tsan,
it needs tid quarantine and reuse counters. Other sanitizers
don't need that. It also seems that no other sanitizer now
needs max number of threads. Asan used to need 2^24 limit,
but it does not seem to be needed now. Other sanitizers blindly
copy-pasted that without reasons. Lsan also uses quarantine,
but I don't see why that may be potentially needed.
Add a ThreadRegistry ctor that does not require any sizes
and use it in all sanitizers except for tsan.
In preparation for new tsan runtime, which won't need
any of these parameters as well.

sanitizer_common: introduce kInvalidTid/kMainTid
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.

[lsan] Add interceptor for pthread_detach.
This commit adds an interceptor for the pthread_detach function,
calling into ThreadRegistry::DetachThread, allowing for thread contexts
to be reused.
Without this change, programs may fail when they create more than 8K
threads.

This is a small refactoring to prepare for porting LSan to Fuchsia.
Factor out parts of lsan_thread.{cpp,h} that don't apply to Fuchsia.
Since existing supported systems are POSIX-based, the affected code
is moved to lsan_posix.{cpp.h}.
