HDRenderPipeline: Add support of shadow mask (Disabled in 2017.3) - require C++ change

- Create clearColorAllBlack to have color with alpha channel with 0 for
clear.
- Add shadowmask and occlusion probe sampling functions
- Add various debug feature for shadow mask
- Refactor GBuffer manager
- Add SHADOWS_SHADOWMASK keyword to our various lit and debug shader
- In deferred, SHADOWS_SHADOWMASK add an extra GBuffer
- Create a BakeLightingData that contain bakeDiffuseLighting +
bakeShadowMask
- Update all lightLoop call with this new BakeLightingData struct, pass
it to EvaluateBSDF_XXX function
- Move #pragma multi_compile from .shader to pass that require it
(unsure if this save variant)
