Reapply "[MemProf] Change histogram storage from uint64_t to uint16_t… (#151431) 
Reapply #147854 after fixes merged in #151398.

Change memory access histogram storage from uint64_t to uint16_t to
reduce profile size on disk. This change updates the raw profile format
to v5. Also add a histogram test in compiler-rt since we didn't have one
before. With this change the histogram memprof raw for the basic test
reduces from 75KB -> 20KB.
