target/arm: don't expose "ieee_half" via gdbstub

While support for parsing ieee_half in the XML description was added
to gdb in 2019 (a6d0f249) there is no easy way for the gdbstub to know
if the gdb end will understand it. Disable it for now and allow older
gdbs to successfully connect to the default -cpu max SVE enabled
