target/arm: Advertise MVE to gdb when present
Cortex-M CPUs with MVE should advertise this fact to gdb, using the
org.gnu.gdb.arm.m-profile-mve XML feature, which defines the VPR
register. Presence of this feature also tells gdb to create
pseudo-registers Q0..Q7, so we do not need to tell gdb about them
separately.
NB: the gdb patches to implement this have not yet landed in
gdb upstream, so this patch is RFC status only until that
happens and the XML is finalized.
