Cleanup: move bpy_extras.keyconfig_utils to own module

bpy_extras were meant to be useful high-level helper functions for
script authors to perform common operations,
to avoid writing to verbose API's.

bpy_extras.keymap_utils contains some specialized API calls
mainly intended for Blender's own internal use.

Move keymap import export to internal API.
