Bug: b/118742766
Update gn_to_bp to write an Android.bp file that will build a host-side
Skia library.
Switch some methods from SK_BUILD_FOR_ANDROID to
SK_BUILD_FOR_ANDROID_FRAMEWORK.
Prior reviews were done at ag/5482397.
gn_to_bp.py:
- Run GN twice - once for android and once for linux
- Disable GPU (depends on a to-be-written host side GL target) and HEIF
(which relies on Android hardware) on linux
- TODO: Turn on GPU on linux
- Split sources into everywhere, android-only, and linux-only.
It seems that Android.bp does not allow using the same cpp
file in multiple targets.
- note that we currently *only* divide out the sources. The cflags are
the same (except for a couple manual ones) and include
directories are mostly the same (again, except for manual ones).
Android has a "gpu" include directory, which I don't expect to
make a difference to the linux build, which isn't using GPU (yet).
- Use the same "custom empty" font manager on the host as on Android
- Write separate SkUserConfig files; one for android and one for linux.
This allows libskia to force libraries that use it to use the right
defines by setting export_include_dirs.
- Add extra checks to SkUserConfig.h to ensure we have only the
appropriate SK_BUILD_FOR macro defined
- Add host_supported: true for libskia
gn_to_bp_utils.py:
- Switch SkUserConfig.h from include guards to pragma once so it is
easier to append to the end. This matches how Android generally
includes headers.
BUILD.gn:
- Add skia_use_fixed_gamma_text so host build can use the same SK_GAMMA
defines as the device.
SkPreConfig.h:
- Stop making SK_BUILD_FOR_ANDROID_FRAMEWORK imply SK_BUILD_FOR_ANDROID.
The host build needs the former defined but not the latter.
SkRegion.cpp/.h:
- Make toString() SK_BUILD_FOR_ANDROID_FRAMEWORK so it can be called on
the host.
SkCamera.h/.cpp:
- Switch methods to SK_BUILD_FOR_ANDROID_FRAMEWORK so they can be called
on the host.
- Make getCameraLocation*() const. They are logically const, and this
allows removing a const_cast + TODO in hwui.

- add AVX-512 to SK_CPU_SSE_LEVEL
- remove unused SK_ARM_ARCH
- small formatting changes
- no need to check for __ARM_NEON__ and __ARM_NEON...
__ARM_NEON is defined anywhere we'll find NEON.

Lots of completely unused bits and bobs removed.
I've decided SK_SUPPORT_UNITTEST and its single use are not
very compelling.
tests/CPlusPlusEleven was the only user of Sk32ToBool(),
and no longer generally needed.

When targetting iOS and using gyp to generate the build files, it is not
possible to select files to build depending on the architecture. Due to
that, the skia code was disabling all optimisation when SK_BUILD_FOR_IOS
was defined.
Since it is possible to select the correct optimised version when using
gn, this pessimisation is hurting the build. Introduce a new define to
disable the optimisation SK_BUILD_NO_OPTS. It will be used by Chromium
when building skia for iOS with gyp but not gn.
Define SK_BUILD_NO_OPTS along-side SK_BUILD_FOR_IOS for all files that
look like build configuration (Xcode projects, gyp configuration files,
public.bzl) in order to avoid introducing breakage on those builds.

This is more general than checking for __linux, __FreeBSD__, etc. (In
principle we could remove some of the existing checks such as
__FreeBSD__, but I have not tried that so far.)
In particular, it allows Skia to build with the NaCl or PNaCl
toolchains, which is something we would like for Mojo.

CL (1 of 3) adds empty lists in our .gypi,
and builds the files in those empty lists with the appropriate flags.
CL (2 of 3) will have Chrome's GYP and GN files read these lists,
and build them with the appropriate flags.
CL (3 of 3) will add runtime detection and stub files to the lists
with empty Init_sse42(), Init_avx(), Init_avx2() methods.
After that, we should be able to use SSE 4.2, AVX, and AVX2 if desired.
Some motivation:
- SSE 4.2 adds some sweet string-oriented methods that
can help us write fast high quality 32-bit hashes.
- AVX is SSE doubled, e.g. 8 floats or two SkPMFloat at a time.
- AVX2 is SSE2 doubled, e.g. 8 pixels at a time.

SDL isn't an OS anyway, it's just a library views can use. Remaining
support for Brew was removed some time ago, and there are currently
no uses of SK_BUILD_FOR_PALM.

This hasn't been tested for years, and no one currently knows when it
last worked (if ever). It is doubtful that any of the remaining logic
would even make sense with a modern version of Embedded Compact 2013.

The implementation is nearly identical to Sk2f, with these changes:
- float32x2_t -> float64x2_t
- vfoo -> vfooq
- one extra Newton's method step in sqrt().
Also, generally fix NEON detection to be defined(SK_ARM_HAS_NEON).
SK_ARM_HAS_NEON is not being set on ARM64 bots right now (nor does the compiler
seem to set __ARM_NEON__), so this CL fixes everything up.

Aarch64 support
This change contains the necessary modifications to have Skia build and
run properly on an ARMv8 processor in aarch64 execution state.
Here's a list of the changes:
- add an arm64 target to the build system + SK_CPU_ARM64 flag
- MatrixTest was failing when built in Release mode. Fused MAC
instructions were generated which made some intermediate results
more accurate. As the test relies on result comparison, the more
precise results when compared to others led to a gap bigger than
what was tolerated. As I don't know if some actual skia code relies
on results being comparable, I've disabled fused MAC instruction
with -ffp-contract=off for arm64.
- Modify include/core/SkOnce.h to have barriers work.
- SK_CPU_ARM64 implies SK_ARM_NEON_MODE_ALWAYS.
- use existing Xfermode optimisations with modifications that can be
removed in the future when toolchains are ready. Also save a few
instructions is two Xfermodes (will apply to ARM too).
- use existing SkBoxBlur and SkMorphology optimisations.
- use existing SkBlitMask optimisations
- use existing BitmapProcState and Convolution optimisations.
Future changes will include:
- Blitters (only partialy merged upstream)
- SkUtils (there's little value in sending asm optimisations without
having them benchmarked on real hardware).
