igt: tests: chamelium: Convert VGA tests to do_test_display

The VGA tests were run so far as part of a separate function. However,
the only difference between that function and the do_test_display
function was the kind of comparison we wanted to use. Indeed, VGA
being an analog output, we can't rely on a pixel perfect image, and
thus only compare the CRCs, but we need to make some more advanced
comparison.

Let's add a new check method, add support for the analog check to
do_test_display and remove the old version.
