This is purely for convenience, to not need to write the lock type
in the guard anymore. This should all inline away.

Proposed policy:
- If the target is *legacy* (e.g. L32/PMColor) ignore gamma
- If the target is S32/F16 respect gamma

On my Mac (so, immintrin), this improves compile time, both wall and cpu,
by about 16%. To test I ran this on an SSD with files hot in their caches:
$ env CC=/usr/bin/clang CXX=/usr/bin/clang++ ./gyp_skia && \
ninja -C out/Release -t clean && \
time ninja -C out/Release
Before: 159 wall / 3367 cpu
159 wall / 3368 cpu
After: 137 wall / 2860 cpu
136 wall / 2863 cpu
I also tried further refining immintrin down to emmintrin / tmmintrin / smmintrin etc.
That made no signficant difference, so I've kept immintrin for its simplicity.

Convert use of GrFragmentProcessor, GrGeometryProcessor, and
GrXPFactory to sk_sp. This clarifies ownership and should
reduce reference count churn by moving ownership.

- remove dead code
- rewrite float -> int converters
The strategy for the new converters is:
- convert input to double
- floor/ceil/round in double space
- pin that double to [SK_MinS32, SK_MaxS32]
- truncate that double to int32_t
This simpler strategy does not work:
- floor/ceil/round in float space
- pin that float to [SK_MinS32, SK_MaxS32]
- truncate that float to int32_t
SK_MinS32 and SK_MaxS32 are not representable as floats:
they round to the nearest float, ±2^31, which makes the
pin insufficient for floats near SK_MinS32 (-2^31+1) or
SK_MaxS32 (+2^31-1).
float only has 24 bits of precision, and we need 31.
double can represent all integers up to 50-something bits.
An alternative is to pin in float to ±2147483520, the last
exactly representable float before SK_MaxS32 (127 too small).
Our tests test that we round as floor(x+0.5), which can
return different numbers than round(x) for negative x.
So this CL explicitly uses floor(x+0.5).
I've updated the tests with ±inf and ±NaN, and tried to
make them a little clearer, especially using SK_MinS32
instead of -SK_MaxS32.
I have not timed anything here. I have never seen any of these
methods in a profile.

It's always nice to kill off a synchronization primitive.
And while less terse, I think this new code reads more clearly.
... and, SkOncePtr's tests were the only thing now using sk_num_cores()
outside of SkTaskGroup, so I've hidden it as static inside SkTaskGroup.cpp.

I think this version reads more clearly, and the key invariants are
expressed in code rather than comments:
- race losers always go through an acquire
- we never exit the function unless fState is Done

- 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.

Still slowly working through all the SK_DECLARE_STATIC_FOO macros.
SkOncePtr is complicating things by having SkOncePtr delete its pointer
and SkBaseOncePtr not. Simplify things by removing SkOncePtr, leaving
only the leaky SkBaseOncePtr.
We replace SkOncePtr<T> instead with SkOnce and T. In most cases this
did not need to be a pointer, and in some cases here we're even saving
a few bytes by replacing SkOncePtr<T> with SkOnce and a T.
The dependency map of SK_DECLARE_STATIC_FOO is:
SkBaseMutex -> SkBaseSemaphore -> SkBaseOncePtr
They're intertwined enough that I think I've got to do all three in one
next CL.

This uses the same logic we worked out for SkOncePtr to reduce
the memory footprint of SkOnce from a done byte and lock byte
to a single 3-state byte:
- NotStarted: no thread has tried to run fn() yet
- Active: a thread is running fn()
- Done: fn() is complete
Threads which see Done return immediately.
Threads which see NotStarted try to move to Active, run fn(), then move to Done.
Threads which see Active spin until the active thread moves to Done.
This additionally fixes a too-weak memory order bug in SkOncePtr,
and adds a big note to explain.

SkTArray cannot currently contain move only elements because its swap
currently requires the SkTArray to be copyable. This makes SkTArray
movable and makes its swap move instead of copy.

The API and implementation are very much simplified.
You may not want to bother reading the diff.
As is our trend, SkOnce now uses <atomic> directly.
Member initialization means we don't need SK_DECLARE_STATIC_ONCE.
SkSpinlock already works this same way.
All uses of the old API taking an external bool* and Lock* were pessimal,
so I have not carried this sort of API forward. It's simpler, faster,
and more space-efficient to always use this single SkOnce class interface.
SkOnce weighs 2 bytes: a done bool and an SkSpinlock, also a bool internally.
This API refactoring opens up the opportunity to fuse those into a single
three-state byte if we'd like.
No public API changes.
