Keymap: update addon register/unregister utilities

Use the same data format and loader that the default key-maps use.

This supports nested properties (needed for macros)
and fixes modal key-maps which weren't supported.

This format still needs to be documented.

 # Add-on helpers to properly (un)register their own keymaps.
 
-# Example of keymaps_description:
-keymaps_description_doc = """
-keymaps_description is a tuple (((keymap_description), (tuple of keymap_item_descriptions))).
-keymap_description is a tuple (name, space_type, region_type, is_modal).
-keymap_item_description is a tuple ({kw_args_for_keymap_new}, (tuple of properties)).
-kw_args_for_keymap_new is a mapping which keywords match parameters of keymap.new() function.
-tuple of properties is a tuple of pairs (prop_name, prop_value) (properties being those of called operator).
-
-Example:
-
-KEYMAPS = (
-    # First, keymap identifiers (last bool is True for modal km).
-    (('Sequencer', 'SEQUENCE_EDITOR', 'WINDOW', False), (
-    # Then a tuple of keymap items, defined by a dict of kwargs for the km new func, and a tuple of tuples (name, val)
-    # for ops properties, if needing non-default values.
-        ({"idname": export_strips.SEQExportStrip.bl_idname, "type": 'P', "value": 'PRESS', "shift": True, "ctrl": True},
-         ()),
