1. Bug 1607746 - Part 1: Move opacity to its own shader in WebRender r=n… …

   …ical
   
   Opacity is a common effect that is used and the opacit filter path is also used when a stacking
   context has an opacity of < 1. The brush_blend shader is slow since it has support for a large
   portion of CSS filters; however, opacity is used much more often than the rest of the filters.
   This patch adds a simple shader for opacity effects which bypasses the extra overhead in the
   brush_blend shader.

2. Bug 1607746 - Part 2: Clean up passing filter mode to shader r=nical …

   I removed the old opacity filter path in the brush_blend shader and cleaned up the filter mode
   constants in the shader so there are less magic numbers. This should help if/when we move more
   filters to their own shaders.
