Implement input type configs (#3784)

Add support for configurations that apply to a type of inputs
(i.e. natural scrolling on all touchpads). A type config is
differentiated by a `type:` prefix followed by the type it
corresponds to.

When new devices appear, the device config is merged on top of its
type config (if it exists). New type configs are applied on top of
existing configs.
