Move from using Kconfig GDBSTUB_SERIAL_BACKEND_NAME to a devicetree
chosen property ("zephyr,gdbstub-uart"). This is similar to a number
of other functions like "zephyr,shell-uart" or "zephyr,bt-uart".

In order to bring consistency in-tree, migrate all subsystems code to
the new prefix <zephyr/...>. Note that the conversion has been scripted,
refer to zephyrproject-rtos#45388 for more details.

It implements gdb remote protocol to talk with a host gdb during the
debug session. The implementation is divided in three layers:
1 - The top layer that is responsible for the gdb remote protocol.
2 - An architecture specific layer responsible to write/read registers,
set breakpoints, handle exceptions, ...
3 - A transport layer to be used to communicate with the host
The communication with GDB in the host is synchronous and the systems
stops execution waiting for instructions and return its execution after
a "continue" or "step" command. The protocol has an exception that is
when the host sends a packet to cause an interruption, usually triggered
by a Ctrl-C. This implementation ignores this instruction though.
This initial work supports only X86 using uart as backend.
