gdbstub: add multiprocess support to Xfer:features:read:

Change the Xfer:features:read: packet handling to support the
multiprocess extension. This packet is used to request the XML
description of the CPU. In multiprocess mode, different descriptions can
be sent for different processes.

This function now takes the process to send the description for as a
parameter, and use a buffer in the process structure to store the
generated description.

It takes the first CPU of the process to generate the description.
