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.
