TextureView Vulkan support and optimized OpenGL draw

Render TextureView as hardware bitmaps, instead of GL textures.
Cache SkImage for each observed GraphicBuffer, which is faster
even for GL.
Implement C++ SurfaceTexture, which allows Java SurfaceTexture
to be used with Vulkan HWUI render thread and application GL.
threads. Delete GLLayer and VkLayer classes and texture code
from old HWUI pipeline.

Test: Ran skiagl and skiavk pipeline with a TextureView app.
Test: TextureView CTS tests pass for GL pipeline.
Test: Ran Android NDK Native codec sample app.
