[Research] BLITPERF: Allow the GRCG sprite color to be customized 

spaztron64 suggested that the GRCG might not always write all 4 planes
if one of the tile registers is 0. By changing the color and comparing
the results of this benchmark, we can prove that real hardware has no
such optimization.

Completes P0233, funded by [Anonymous].
