DynamicTablesPkg: Add OEM Info

This patch originally merged in edk2 master at
c788bdaba4. However, this was
later reverted at bdbbedea94
as it was merged during the Soft Feature Freeze for
edk2-stable201903.

Resubmitting this patch as the edk2 merge window is now open.

Added option for OEMs to provide OEM Table ID and
OEM Revision for ACPI tables.
