Guest-Side (TDCALL) Interface Helper Functions

This crate implements the helper functions for the TDCALL interface functions defined in Intel TDX Module specifiction and the TDVMCALL sub-functions defined in Intel TDX Guest-Hypervisor Communication Interface specification. It also provides the constants and data structures that are defined in the specifications.

Please refer to following links for detail: Intel TDX Module v1.0 Spec Intel TDX Module v1.5 Spec Intel TDX Guest-Hypervisor Communication Interface Spec Intel TDX Guest-Hypervisor Communication Interface Spec v1.5

A subset of TDCALL interface functions is defined in crate::tdx, and the TDG.MR.REPORT leaf function and TDREPORT_STRUCT related definitions are defined in crate::tdreport separately.
