Add support for building and installing repo target sets
Introduce the concept of repository target sets, which is a named set of
targets within a Qt module repository.
In a Qt repository, a repo target set 'qtfoo' can be defined in the
top-level project file with
qt_internal_define_repo_target_set(qtfoo DEPENDS Bar Baz)
The DEPENDS argument specifies Qt components that need to be
find_package'd when building the targets that belong to qtfoo.
In subdirectory project files, use
qt_internal_include_in_repo_target_set(qtfoo) to mark the file as
belonging to the repo target set.
To build and install a single repo target set, specify
QT_BUILD_SINGLE_REPO_TARGET_SET=qtfoo when configuring the Qt
repository.
