chamelium: Add format support

In order to introduce CRC subtests for DRM formats, we need to take an
intermediate step.

The current code will generate a pattern in XR24, and will try to compare
the CRC returned by the Chamelium for each frames.

This CRC is computed on an XR24 format as well, so it works. However, as
soon as we will start implementing other formats, if we just change the
format of the pattern, the raw content of the buffer, and therefore the
CRC's won't match anymore.

In order to address that, we will need an intermediate step, and we will
now still create the XR24 pattern, and compute its CRC, then convert it to
the format we want to test, and finally retrieve the CRC from the Chamelium
to compare it with the one from the XR24 pattern.

The current code is converted to the new prototype that will take the
fourcc of the format to test, even though we're still using XR24 everywhere
for now.
