* Add bindings to allow creating multiple physical layouts that specify their key's physical attributes, and the matching matrix transform and dependant kscan to use. * Synthesize a basic physical layout if none specified, for backwards compatibility. * Update matrix transform API to explicitly pass in the selected transform to the API instead of using a fixed chosen transform. * Move kscan subscription and handling into the physical layout code, so that selecting a different physical layout at runtime can also use the correct kscan instance. * Add `physical_layouts.dtsi` file to include so you can use the pre-configured `&key_physical_attrs` for adding you layout keys.
