Coverity reported a memory leak (CID 1549757) in this code and its
admittedly rather clumsy handling of extending the command table.
Instead of handing over a full array of the commands lets use the
lighter weight GPtrArray and simply test for the presence of each
entry as we go. This avoids complications of transferring ownership of
arrays and keeps the final command entries as static entries in the
target code.

Allow passing the current CPU context to command handlers via user_ctx
when the handler requires it.

Make gdb_hextomem non-internal so it's not confined to use only in
gdbstub.c.

Currently, it's not possible to have stubs specific to a given target,
even though there are GDB features which are target-specific, like, for
instance, memory tagging.
This commit introduces gdb_extend_qsupported_features,
gdb_extend_query_table, and gdb_extend_set_table functions as interfaces
to extend the qSupported string, the query handler table, and the set
handler table, allowing target-specific stub implementations.

Move GdbCmdParseEntry and its associated types into a separate header
file to allow the use of GdbCmdParseEntry and other gdbstub command
functions outside of gdbstub.c.
Since GdbCmdParseEntry and get_param are now public, kdoc
GdbCmdParseEntry and rename get_param to gdb_get_cmd_param.
This commit also makes gdb_put_packet public since is used in gdbstub
command handling.
