Use pre-compiled headers when building Qt with cmake
Some modules define their own manually-maintained lists, and we can rely
on the headers generated by each module to include in the pch as well
e.g. QtCore/QtCore.
There's also e.g. QtWidgetDepends for QtWidgets, but this only
works for modules, not for tools, examples or other applications.
For now we'll use the Qt<Module>/Qt<Module> headers for the
modules we depend on.
Building with PCH can be disabled with -DBUILD_WITH_PCH=NO, and it only
works for versions of CMake newer than 3.15.20190829.
