Generalize iterator in GrTAllocator to be useful for other data types

This allows the iterator type/boilerplate to be reused for any other
data collection that sits above GrBlockAllocator, as long as its a fixed
"type" with indices into a block.

Also adds reverse iteration (which is useful for stack-like use cases).
