Teach TSAN directly about semaphore_t.
...
Instead of teaching TSAN than SkMutex is a lock to get around it not
understanding Mach semaphore_t routines, teach it that there is a
happens-before relationship between semaphore_signal() and
semaphore_wait().

Mac TSAN support: annotate Sk[Base]Mutex as a mutex.
...
TSAN does not intercept Mach semaphore_t calls used to implement
SkBaseMutex's fSemaphore (its OSSemaphore field). We can teach
it that Sk[Base]Mutex is a mutex anyway with the same annotations
we use for SkSharedMutex.

Type-erase SkAutoMutexAcquire and SkAutoExclusive.
...
This is purely for convenience, to not need to write the lock type
in the guard anymore. This should all inline away.

Modernize SkMutex and SkSemaphore.
...
- use <atomic>
- fuse SkMutex and SkBaseMutex
- fuse SkSemaphore and SkBaseSemaphore
Still TODO:
- replace SK_DECLARE_STATIC_MUTEX(name) with static SkMutex name
I just didn't want to bother fixing all that up until I know this CL sticks.

Revert of Modernize SkMutex and SkSemaphore. (patchset #2 id:20001 of https://codereview.chromium.org/1947153002/ )
...
Reason for revert:
This CL seems to have broken the Linux x64 and Mac
bots, e.g.
https://build.chromium.org/p/chromium/builders/Linux%20x64/builds/19052
https://build.chromium.org/p/chromium/builders/Mac/builds/15151
The error appears to have something to do with new static initializers being
added.
