kms_frontbuffer_tracking: add scaledprimary subtest

Browse Source 
It's not testing a lot since we lack the Kernel Stolen Memory Checker,
but some day this will be useful.

/*
* scaledprimary - try different primary plane scaling strategies
*
* METHOD
* Enable the primary plane, use drmModeSetPlane to force scaling in
* different ways.
*
* EXPECTED RESULTS
* SKIP on platforms that don't support primary plane scaling. Success on all
* others.
*
* FAILURES
* TODO: although we're exercising the code here, we're not really doing
* assertions in order to check if things are working properly. The biggest
* issue this code would be able to find would be an incorrectly calculated
* CFB size, and today we don't have means to assert this. One day we might
* implement some sort of stolen memory checking mechanism, then we'll be able
* to force it to run after every drmModeSetPlane call here, so we'll be
* checking if the expected CFB size is actually what we think it is.
