OvmfPkg/BaseMemEncryptSevLib: remove Flush parameter BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3275 The Flush parameter is used to provide a hint whether the specified range is Mmio address. Now that we have a dedicated helper to clear the memory encryption mask for the Mmio address range, its safe to remove the Flush parameter from MemEncryptSev{Set,Clear}PageEncMask(). Since the address specified in the MemEncryptSev{Set,Clear}PageEncMask() points to a system RAM, thus a cache flush is required during the encryption mask update.

OvmfPkg/BaseMemEncryptSevLib: introduce MemEncryptSevClearMmioPageEncMask() BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3275 The MemEncryptSevClearMmioPageEncMask() helper can be used for clearing the memory encryption mask for the Mmio region. The MemEncryptSevClearMmioPageEncMask() is a simplified version of MemEncryptSevClearPageEncMask() -- it does not flush the caches after clearing the page encryption mask.

OvmfPkg/MemEncryptSevLib: Address range encryption state interface BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3108 Update the MemEncryptSevLib library to include an interface that can report the encryption state on a range of memory. The values will represent the range as being unencrypted, encrypted, a mix of unencrypted and encrypted, and error (e.g. ranges that aren't mapped).
