  [MemProf][NFC] Compute SHADOW_ENTRY_SIZE from MEM_GRANULARITY and SHADOW_SCALE

As MEM_GRANULARITY represents the size of memory block mapped to a single shadow entry,
and SHADOW_SCALE represents the scale of shadow mapping,
so the single shadow entry size can be computed as (MEM_GRANULARITY >> SHADOW_SCALE).

This patch replaces the hardcoded SHADOW_ENTRY_SIZE with (MEM_GRANULARITY >> SHADOW_SCALE).
