Add CPU_TYPE_ARM64
This is distinct from CPU_TYPE_ARM, since we're going to exclusively use
AArch64 / A64, which CPU_TYPE_ARM was never meant to support, and to
match EM_AARCH64, which is also separate from EM_ARM. CPU_TYPE_X86_64
was similarly made distinct from CPU_TYPE_I386.
This is named CPU_TYPE_ARM64 rather than CPU_TYPE_AARCH64, since AArch64
is an "execution state" (analogous to long mode on x86_64) rather than a
CPU type. "ARM64" here is not a name of the architecture, but simply
means an ARM CPU that is capable of (and for our case, will only really
be) running in the 64-bit mode (AArch64).
There are no subtypes defined, and none are expected to be defined in
the future. Support for individual features/extensions should be
discovered by other means, i.e. the aarch64_get_hwcaps() RPC.
