Adopt the Qt dependencies lookup mechanism for tools dependencies

The existing lookup mechanism doesn't consider Qt path when looking for
the Qt Tool package dependencies. In good scenario this leads to the
missing Qt Tool package, in worst case scenario the Tool package could
be found by alternative search path and attempt using the invalid
tools.

Use the lookup functionality we have for Qt modules when looking for
dependencies of the Qt tools. This will look the tools in Qt search
paths first and only then attempt looking elsewhere, considering the
QT_HOST_PATH.
