Destroying a mutex while it is held is never valid, and can be extremely
hard to debug.

The automatic copy and move constructors and such are not appropriate
for this type. It could be refactored to be movable but not copyable,
but as written it's neither.

Remove the SkBaseMutex (and SkBaseSemaphore). This allows all the thread
annotation machinery to work.

Introduce SkAutoMutexExclusive for SkMutex RAII.
Unsubclass SkMutex from SkBaseMutex to allow annotations
for class field mutexes separate from global mutexes.
Leave SkAutoMutexAcquire for handling global mutexes using
SkBaseMutex.
Test using GrSingleOwner.h.

Current strategy: everything from the top
Things to look at first are the manual changes:
- added tools/rewrite_includes.py
- removed -Idirectives from BUILD.gn
- various compile.sh simplifications
- tweak tools/embed_resources.py
- update gn/find_headers.py to write paths from the top
- update gn/gn_to_bp.py SkUserConfig.h layout
so that #include "include/config/SkUserConfig.h" always
gets the header we want.

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().
This reverts commit e395bf2d18.
New changes are entirely restricted to SkSemaphore.cpp.

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.
