The purpose of this change is to refactor the handling of normal maps out of SkLightingShader, laying the groundwork to eventually allow for multiple normal sources.
What this CL includes:
- Created a new 'NormalMapFP', out of the existing normal map reading behavior in LightingFP.
- Encapsulates this new fragment processor on a new class NormalMapSource.
- Created a NormalSource abstraction that will interface with SkLightingShader.
- Adapted SkLightingShader to use the normals from its NormalSource field ON THE GPU SIDE. No changes done to the CPU side yet.

SkPicture::cullRect() is not guaranteed to be the same as the
bounds passed to SkPictureRecorder::beginRecording().

Reason for revert:
Breaks a couple Google3 goldens. I need to rebaseline google3 with -DSK_SUPPORT_LEGACY_X86_BLITS first, then reland this.

Currently, Skia always uploads GPU textures at full resolution. This
change allows us to pass a pre-scale mip level to the
deferred texture image logic, which causes us to pre-scale the image
to the given mip level, and upload that mip level instead of the full
image.

This code was running on our bots but never in Chrome.
That's a bad state to be in.
My plan here use to be to redesign how our 8888 blits worked in SSE 4.1, mainly
for perfect correctness but also for speed, then to spread what I learned there
to SSE2, AVX+, and NEON.
I have since lost interest in changing any aspect of how our legacy 8888 blits
work. There's not much point in making them a bit or two more correct when the
math is fundamentally wrong.
This will cause many diffs in Gold, none perceptible.

Tried to comment my logic, but it's totally possible that we run on some
device where this doesn't work. From a strict reading of the relevant
specs, what I'm doing shouldn't work on the Nexus 5X, but it's necessary
to get correct results.

To build shaderc, gyp used to punt to cmake, which did not work well on the bots and I couldn't find any way to pipe the variables into cmake which would have made it happy.
So, I wrote a gyp file for shaderc and its dependencies. Nothing super complicated (thank goodness), except for the files that spirv-tools needed generated.

The custom font manager does not implement all onCreateFromStream
overloads leading to warnings. Since this needs to be implemented
anyway, implement it now.

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.
