fix(gic): Add missing check to gicv3_hcr field

-> This patch adds the missing check for must be set to
   '0' fields in entry.gicv3_hcr upon REC entry.
-> Entry structure is validated before copying to Rec structure.
-> Rename the gic_copy_state_from_ns() and gic_copy_state_to_ns() as it
   is not directly accessing NS memory but an internal RMM copy.
