Doc: Fix documentation warnings related to Clang QDoc parser

Since Qt 5.11, QDoc uses Clang to parse C++ documentation. Clang
requires a module header, as well as proper include paths, to
build a precompiled header and process the sources.

To do this, add a custom module header that pulls in all Qt 3D modules
- this way, we can continue using a single documentation project to
covers all of Qt 3D.

Fix all documentation warnings are caused by missing namespaces, QML
module/type names and typos, as well as a number of linking problems
and other minor issues.

After this change, the remaining documentation issues consist of
'No documentation for ...' warnings.
