[vulkan] Change shadow quanta to 128 pixels

Browse source 
Interestingly, this caused a reduction in memory use for some maps (but
did increase marcher's again, but not as much as the bogus rounding
did). The idea was to use sparse bindings to remap shadow map layers,
but it turns out sparse bindings are insanely slow (beyond unusable).
However, the reduction in the number of shadow map images seems to be
worth it.
