ShellPkg: acpiview: Add library for SBBR ACPI requirements validation

For Arm-based platforms, define and implement an interface for Server
Base Boot Requirements (SBBR) compliance checks. The library is
responsible for validating that all mandatory ACPI tables are installed
on the platform.

Internally, the library maintains a data structure which tracks
instance counts for ACPI tables which are labeled as 'mandatory' in any
SBBR specification version. The provided interface allows:
- resetting all instance counts to 0
- incremementing the instance count for a table with a given signature
- validating the instance counts against the requirements in SBBR

The ACPI table requirements for each SBBR spec version are represented
internally as a list of table signatures.

Every missing mandatory table (for the input SBBR version) is reported
to the user as a separate error. If all requirements are met, an info
message is displayed.
