[qt5] Do not link all .lib files

This commit moves a few .lib files to subfolders to prevent them from
automatically getting linked:

Qt5Bootstrap (dbg):
This lib is linked against a release version of the CRT and is only
meant for release builds. For debug builds, this lib should not be
linked at all.

qtmain (rel), qtmaind (dbg),
Qt5AxServer (rel), Qt5AxServerd (dbg):
These libs are mutually exclusive. The user either links against
qtmain(d) for desktop applications or against Qt5AxServer(d) for ActiveX
servers.

See https://github.com/Microsoft/vcpkg/issues/1442 for more information.

+#file(REMOVE ${CURRENT_PACKAGES_DIR}/debug/lib/Qt5Bootstrap.lib)

+# Above approach does not work: 
+#   check_matching_debug_and_release_binaries(dbg_libs, rel_libs)
+# requires the two sets to be of equal size!
+# Alt. approach, create dummy folder instead:
