Alexandru Croitor 9061f29872 Provide a way to specify extra tool package dependencies
In the qtwayland repo, both WaylandClient and WaylandCompositor
packages need access to the qtwaylandscanner tool. That means
that the add_qt_tool(qtwaylandscanner) can't use the TOOLS_TARGET
argument to associate a dependency with only one of the above
modules.

Instead add_qt_tool now allows specifying a non-existent module
name for the TOOLS_TARGET argument, which can be manually
depended on by other packages.
Actually, you could specify the non-existent module before as
well, but that didn't do everything that had to be done.

This required a bit of refactoring in how the Dependencies file
for Tools packages is created. Now the file is created in
qt_export_tools.

Two new functions were also added to allow recording additional
dependencies between packages.

Also some bug fixes were done to make it all work. Specifically
the _FOUND variable generated in the Dependencies file was incorrect.
Also there are some quotes missing when appending extra package
dependencies via the QT_EXTRA_PACKAGE_DEPENDENCIES property.
