aarch64: rcpc3: Add +rcpc3 architectural feature support flag
Indicating the presence of the Armv8.2-a feature adding further
support for the Release Consistency Model, the `+rcpc3' architectural
extension flag is added to the list of possible `-march' options in
Binutils, together with the necessary macro for encoding rcpc3
instructions.
