gdb: add context getter/setter to cmd_list_element

Straightforward replacement of get_cmd_context / set_cmd_context with
cmd_list_element methods.

gdb/ChangeLog:

	* cli/cli-decode.h (struct cmd_list_element) <set_context,
	context>: New.
	<context>: Rename to...
	<m_context>: ... this.
	* cli/cli-decode.c (set_cmd_context, get_cmd_context): Remove.
	* command.h (set_cmd_context, get_cmd_context): Remove, use
	cmd_list_element::set_context and cmd_list_element::context
	everywhere instead.
