target/arm: use official org.gnu.gdb.aarch64.sve layout for registers
While GDB can work with any XML description given to it there is
special handling for SVE registers on the GDB side which makes the
users life a little better. The changes aren't that major and all the
registers save the $vg reported the same. All that changes is:
- report org.gnu.gdb.aarch64.sve
- use gdb nomenclature for names and types
- minor re-ordering of the types to match reference
- re-enable ieee_half (as we know gdb supports it now)
- $vg is now a 64 bit int
- check $vN and $zN aliasing in test
