src/3rdparty: remove xkbcommon

The only reason why we bundled this library ~6 years ago was because
it was not available on distributions that we supported at the time,
but library was a hard dependency for XCB plugin. See:
2122e731abdb619249df89642c0800640b2fa428

Later more and more projects started to depend on it (compose input
context plugin, libinput, mir, wayland). The configuration had become
too complex, because some projects used bundled and some used the
version from the system.

Having libxkbcommon in 3rdparty sources is not necessary anymore, after
RHEL 6.6 was removed from the list of supported platforms for Qt 5.12.

Ubuntu 16.04  - 0.5.0
Ubuntu 18.04  - 0.8.0
openSUSE 42.3 - 0.6.1
RHEL-7.4      - 0.7.1

This will also simplify further development, e.g. QTBUG-42181

Bumped the minimal required version 0.4.1 -> 0.5.0.

The patch also contains a code marked with "TRANSITION HACK", which
is temporary needed so we can update the dependent wayland module.

[ChangeLog][Third-Party Code] Removed xkbcommon from bundled sources.
This library is present on all supported platforms. The minimal required
version now is 0.5.0.
