DynamicTablesPkg: Fix conversion compiler warnings

Some CM objects fields are wider than the targeted field in ACPI
tables. Some assignments are also subject to data loss and
trigger the following warnings:
- '<': signed/unsigned mismatch
- '=': conversion from 'UINTxx' to 'UINTyy', possible loss of data
with xx > yy.

Add checks/cast to remove the warnings.
