target/arm: Inform helpers whether a PAC instruction is 'combined'

An instruction is a 'combined' Pointer Authentication instruction
if it does something in addition to PAC -- for instance, branching
to or loading an address from the authenticated pointer.

Knowing whether a PAC operation is 'combined' is needed to
implement FEAT_FPACCOMBINE.
