[PATCH] hidclass.sys: Only send WM_INPUT messages for HID devices.

[Rémi Bernon]

And not for the internal WINEXINPUT devices.

This should fix a high CPU usage introduced by the winexinput devices,
especially for controller which send a lot of reports.

Sending the messages makes __wine_send_input try finding a device with
the provided rawinput handle, and as it only lists HID, mouse and
keyboard device class interfaces, it never finds it. This makes it
re-enumerate the device list every time, looking for a possible new
device, in vain.

We don't use WM_INPUT messages in xinput, so they aren't needed and we
can just save a few wineserver requests. The &IG_00 device will send its
own WM_INPUT messages anyway.
