HID: add support for Microsoft Natural Ergonomic Keyboard 4000
This keyboard emits a few usages that are not handled properly by
hid-input.
The usages from MSVENDOR page are colliding with Chicony Tactical
Pad device, so we have to distinguish in runtime. Ugly ...
Also, the buttons 1-5 have to be handled in a non-standard way,
as they are emitted by the keyboard in a bitfield-like fashion, but
the field is not presented as bit-field by the keyboard. The keys can't
be pressed simultaneously, so the handling we have is correct.
This patch also extends hid_keyboard[] with KPLeftParenthesis and
KPRightParenthesis as defined by Keyboard page in HUT 1.12. The
corresponding usages are also emitted by this keyboard.
