Add xcb-xinput to 3rd party libs

The added xcb-xinput code was produced by build of libxcb 1.13
with xcb-proto 1.13.
The following parts were removed from it:
 - Pointer Barriers API (requires xcb-xfixes 1.9 with xcb-proto 1.9)
 - SendExtensionEvent API (requires definition of xcb_raw_generic_event_t
   from libxcb 1.13)

[ChangeLog][Third-Party Code] Sources of xcb-xinput 1.13 were bundled and
are available via -qt-xcb.
