OvmfPkg/BaseMemEncryptTdxLib: Add TDX helper library
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429
Add Intel Tdx helper library. The library provides the routines to:
- set or clear Shared bit for a given memory region.
- query whether TDX is enabled.
Please be noted, there a lot of duplicated codes for Page Table
operations. These codes should be moved to a common library
(PageTablesLib) so that it is more friendly for review and maintain.
There is a new feature requirement
https://bugzilla.tianocore.org/show_bug.cgi?id=847 which is to
implement the library. After the lib is introduced, BaseMemEncryptTdxLib
will be refactored.
