Allan Sandfeld Jensen eaf20420f8 Fix precompiled headers with clang-cl
Clang-cl couldn't find the header given to it by -FI when it isn't in
any of the included directories.

Additionally clang-cl 8 has a bug with exported templated classes with
inline methods that causes it to have missing symbols at link time. We
work around this.

Fixes: QTBUG-74563
