3rdparty: remove xcb libs and bump minimal required version to 1.11

With libxcb 1.11 as minimal required version we can:

(a) (Maybe) Enable threaded GL for MESA, see QTBUG-67277.

(b) Avoid performance issues described in QTBUG-46017. Bundled xcb libs don't
    contain the more modern SHM fd passing APIs. The official binaries use
    "-qt-xcb", therefore we were shipping with the performance fix #ifdef-ed out.

(c) Make xcb-xkb a mandatory dependency avoiding issues described in QTBUG-30911.
    Issues that appear when Qt was configure with "-no-xkb -xcb-xlib", but
    X server has the XKB extension.

(d) Drop all, but xcb-xinput sources from src/3rdparty/xcb/, for which
    we need "xcb-xinput >= 1.12". This way we can reduce maintenance
    work. The xcb libraries were origianlly bundled because of lack of availability
    on supported distributions. This is not the case anymore:

    CI for Qt 5.13 has:

      Ubuntu 18.04 - libxcb 1.13
      RHEL 7.4 - libxcb 1.13
      openSUSE 15.0 - libxcb 1.13

    CI for Qt 5.12 has:

      Ubuntu 16.04 - libxcb 1.11
      RHEL 7.4 - libxcb 1.13
      openSUSE 42.3 - libxcb 1.11
      RHEL 6.x - not relevant because it was dropped from supported platforms.

Why 1.11 (released on Aug, 2014), but not 1.13 (released on March 2018)?

Based on what we have in CI for 5.13 and 5.14 we could update to 1.13,
but it means that Qt would require a very recent version of 3rd party
dependency.

[ChangeLog][Configure][X11] The minimal required version of libxcb now is 1.11.

[ChangeLog][Third-Party Code][X11] Removed all bundled XCB libs, with
the exception of xcb-xinput, which is not available on systems with
libxcb 1.11.

[ChangeLog][Configure][X11] Removed -qt-xcb, -system-xcb, -xkb, -xcb-xinput switches.

[ChangeLog][Platform Specific Changes][X11] XKB and XInput2 now are mandatory
dependencies for XCB plugin. XCB-XKB is a part of libxcb 1.11 releases.
XCB-XInput is not part of libxcb 1.11 releases, but Qt builders can use
-bundled-xcb-xinput switch.
