ShellPkg: acpiview: Add support for parsing FACS

Browse Source 
Add support for parsing the ACPI FACS table.

The FADT parser has also been updated as it
links the FACS table using the FIRMWARE_CTRL
or X_FIRMWARE_CTRL fields.

Since the FACS table does not follow the standard
ACPI header, the FADT parser extracts the FACS
signature, length and version fields before invoking
the FACS parser.
