lupdate: check for clang in environment

The configure.pri and configure.json files,
originally located in qttools/src/qdoc,
are moved to qttools/global.
This makes the clang environment accessible
to both qdoc and lupdate.
Both files are adapted to the need of the new lupdate clang-based parser.
(see https://wiki.qt.io/Lupdate_clang-based_c%2B%2B_parser#Clang-environment_and_Qt_configuration for details)

Note:
If the clang environment is not adapted to the upcoming lupdate clang-based parser,
nothing will break, the new parser option will simply not be available.
Nothing is changing for qdoc.
