Subject: gdbstub: Add support for MTE in user mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit implements the stubs to handle the qIsAddressTagged,
qMemTag, and QMemTag GDB packets, allowing all GDB 'memory-tag'
subcommands to work with QEMU gdbstub on aarch64 user mode. It also
implements the get/set functions for the special GDB MTE register
'tag_ctl', used to control the MTE fault type at runtime.
