Rémi Bernon d416f1c4ce user32: Increase the default message buffer size. 
The DS4 controllers are sending 563 bytes HID reports by default, this
translates to WM_INPUT messages larger than the default message size.

We would otherwise need an additional server roundtrip on each message,
and these devices are also known to be very verbose and continuously
send HID reports, so we really don't want it.
