Part 1 - support RGB external surfaces for promotion to compositor
surfaces; add new shader permutations to handle all buffer kinds.
Set the promotion flag when the pixel format has no alpha, or when the
texture provider can guarantee all-solid alpha values.

The list of pre-optimized shaders was being generated in a
non-deterministic order, causing large build time regressions. This
sort the list of shaders before writing them to the shaders.rs file.

Move more shader parsing code to webrender_build, so it can be used
both at runtime and build time.
At build time optimize a set of shaders and feature flag combinations,
using glslopt. Some features are skipped because they are not
supported by the gl version, because the optimizer does not support
them, or because webrender does not need them currently.
Use build-parallel to ensure the optimization is performed in parallel
using the make jobserver. Write the optimized shader source to a
hashmap to be used at runtime, in addition to the unoptimized source.

This is an experiment with only image and solid to see what the infrastructure can be like.
If it works out I'll extend the it with more brush types. More work will be needed to get text rendering in there as well.
The multi-brush shader includes all brushes that it potentially needs suport for. Which brushes actually get compiled in is then specified via WR_FEATURE defines.
Since brushes can't have the same names for their entry points, they specify the function to use via a macros (WR_BRUSH_VS_FUNCTION and WR_BRUSH_FS_FUNCTION).

This chanes the shader parsing code to only inject #included shader sources once (the first time) if they are included multiple times.
This will allow some extra flexibility needed by the multi-brush shader.
