Add tests to the cmake build

Use QT_TESTCASE_SOURCEDIR instead of TESTS_SOURCE_DIR.
Introduce Test::HttpServer and Test::Util targets.
Query shared data location from server.

Clean up "shared" resources.

Note QT_TESTCASE_SOURCEDIR must be turned into the canonical form
since the user can call on windows:

"cmake \path\to\foo" instead of "cmake c:\path\to\foo" which
will break all file:// urls.

Note this patch breaks qmake builds.
