MdePkg: Define AARCH64_CPTR_RES1 and AARCH64_CPTR_DEFAULT 

These constants give the set of RES1 bits in CPTR_EL2, as 1s, and the
default value to use for CPTR_EL2 in order to enable all known (or
harmless) features but no unknown ones that require EL2 knowledge. This
will be used by ArmPlatformPkg in the following commit, separated due to
being different packages, even though the combined change is tiny.
