Subject: [PATCH 20/31] Pull dependencies of static libraries in CMake modules

When doing a static build of Qt, the dependencies of the Qt
libraries and plugins itself must be specified when linking
the final application.

With Qt 5.13.0 the support for doing that has been re-added.
However, some pieces are still missing and that's what this
patch provides:

1. Take dependencies of static plugins into account as well
2. Create imported targets for the dependencies to prevent
   CMake from adding wrong `-Wl,-Bstatic` and `-Wl,-Bdynamic`
   linker flags

This patch has been harmonized with official changes, e.g. to
use QMAKE_PRL_LIBS instead of QMAKE_PRL_LIBS_FOR_CMAKE.

See https://github.com/Martchus/PKGBUILDs/issues/86#issuecomment-476840055
for further details on 2.

With Qt 5.14.0 the support for using static libraries seems
to be further improved. I had not time to test whether it
actually works so I keep using my own implemention for now.
That's why this patch now removes a lot of the 5.14.0 and 5.15.0
additions in favour of 'how it used to work'.
