Add GPU_BLACKLIST support to QTestLib

In addition to BLACKLIST, Qt will now look for GPU_BLACKLIST too.
Test cases that are specified as disabled in the GPU blacklist
will be skipped. This is particularly relevant when running tests
on Embedded Linux devices.

For example, the following JSON would configure the test case
glxContextWrap to be skipped on drivers where GL_VENDOR contains
UnstableDriverVendor:

{
    "entries": [ {
            "gl_vendor": "UnstableDriverVendor",
            "features": [ "disable_glxContextWrap" ]
    } ]
}

In contrast to the regular blacklist, GPU-blacklisted test cases are
not run at all. This is because driver problems and instabilities
often lead to crashes.
