allocations: Scale number of work-items in relation to input size (#2336)

Browse Source 
Make the number of work-items proportional to size of the allocation so
we launch more work-items and do less work per work-item as buffer sizes
go up with device capabilities.

To test:
test_allocations multiple 5 buffer
test_allocations single 5 buffer
