BLI_memblock: Refactor for faster iteration and allocation

Remove the clear allocation flag as it has little impact since there should
be very few allocation per redraw.

Make BLI_memblock_alloc and BLI_memblock_iterstep much more cache efficient
removing them almost entirely from performance profiles.
