Extension of the USB HID Usages

[x-ist]

The following patch advances the definitions in /trunk/src/add-ons/kernel/drivers/input/usb_hid of HID Usage Pages along with their Usage IDs to a large extend.

To provide a better overview and accessibility of the defined Usage IDs I decided to move them out of USB_hid.h into separate files, all being included by USB_hid.h. This prepares also for future implementations (e.g. of datastructures possibly required for specific HID Usage Pages).

Usage Pages start with HID_USAGE_PAGE_... Usage IDs start with HID_UID_<pn>_ Here <pn> represents a short version of the usage page.
