DynamicTablesPkg: DynamicPlatRepoLib: Added MemoryAllocationLib to inf

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3996

The DynamicPlatRepoLib has multiple reference to MemoryAllocationLib,
such as DynamicPlatRepo.c and TokenMapper.c. Not including it in the
library inf file could lead to potential build break.

This change added the MemoryAllocationLib into this inf file.
