[Core] `usb_device_state`: consolidate usb state handling across implementations (#24258)

* usb_device_state: add idle_rate, led and protocol

Previously all usb drivers and platform implementations (expect for our
oddball atsam) tracked the same two global variables:

- keyboard_protocol: to indicate if we are in report or boot protocol
- keyboard_idle: for the idle_rate of the keyboard endpoint

And a local variable that was exposed trough some indirection:

- keyboard_led_state: for the currently set indicator leds (caps lock etc.)

These have all been moved into the usb_device_state struct wich is
accessible by getters and setters.

This reduces code duplication and centralizes the state management
across platforms and drivers.

* usb_device_state: reset protocol on reset

The usb hid specification section 7.2.6 states:

When initialized, all devices default to report protocol. However the
host should not make any assumptions about the device’s state and should
set the desired protocol whenever initializing a device.

Thus on reset we should always do exactly that.
