QDoc: Add CMake package information to documentation

This introduces a new command to QDoc, \qtcmakepackage. The command
works exactly like the \qtvariable command.

The command adds a table row in class and namespace documentation
pages. This entry contains

    CMake: find_package(Qt6 COMPONENT Foo)
           target_link_libraries(mytarget PUBLIC Qt::Foo)

...immediately preceding the existing "qmake: += Foo" row.

[ChangeLog][qdoc] Added a new QDoc command, \qtcmakepackage, that
adds CMake snippets to class and namespace documentation.

Fixes: QTBUG-84024
Pick-to: 5.15
