ShellPkg/AcpiView: PCCT Parser

Bugzilla: 3047 (https://bugzilla.tianocore.org/show_bug.cgi?id=3047)

Create a new parser for the PCCT Table.

The PCCT Table is used to describe how the OSPM can
communicate with entities outside the platform. It
describes which memory spaces correspond to which
entity as well as a few of the needed information
to handle the communications.

This new PCCT parser dumps the values and names of
the table fields. It also performs some validation
on the table's fields.
