This series is taken from the SNP RFC. This series defines the GHCBv2

AARCH64 support has been added to BaseRngLib via the optional

Refactor RngDxe to support AARCH64, note support for it in the

The CI on github showed some coding style issues with this series. I will fix
those locally but wait for more review comments before I send a v2.

This series adds functionality to print a dot graph of a PPTT table.
This helps with understanding and debugging PPTT tables.
The dot graph generator functionality is generic and could be used by
other tables that would benefit from graph output.
