Rename rasterOperation() to blendColor()

rasterOperation was derived from ROP, but that acronym now stands for
'render output unit', and is also understood to include depth value
handling, while our function only performs color blending and writing.

Note that VkPipelineColorBlendAttachmentState also includes the write
mask, so the color blending can be interpreted as also including the
write operation.

Our actual blend operation, without the write, happens in alphaBlend(),
which could be confused for being just the blending of the color's alpha
component, but this is kept as-is for now.
