Keymap: add support for key-config preferences

This is needed for keymaps to define their own options,
which can include left/right mouse select.

This can also help to us to provide popular keymap tweaks as options,
so users can easily fit blender to their workflow with well supported
adjustments which don't give the overhead of having to maintain
your own keymap, which become out-dated when operators change.
