Most of the time we will only be updating either the number of samples
or whether it should be disabled, not both, and we don't need to compare
both. With pipelines we were comparing both, but with dynamic
rasterization samples we want to only update disable when binding the
pipeline and only update samples when calling
vkCmdSetRasterizationSamplesEXT(). Stop optimizing the uncommon case
where both are changed when binding a pipeline, and split it into 2
parts while sharing the common part that records and emits the state
packet.
