Include multisample handling into fragment pipeline stages

Previously we had loops around the stencil test, stencil write, and
depth write, for handling each sample. This change refactors the
methods that implement these fragment pipeline stages to each handle
multisampling on their own. This improves readability, and may reveal
opportunities to optimize multisampling without looping.

cMask, the coverage mask, was eliminated from the stencilTest parameter
list because sMask, the mask for fragments that pass the stencil test,
is already initialized to cMask (just like zMask for the depth test).
