[PATCH i-g-t v1 12/25] lib/chamelium/v2: Extract chamelium v2 wrapper into its own directory

[Mohammed Bilal <mohammed.bilal@intel.com>]

From: Louis Chauvet <louis.chauvet@bootlin.com>

In preparation for the Chamelium v3, the support for Chamelium v2 is being
extracted into its own directory.

The two Chamelium versions have different sets of functionality (audio,
MST, CRC computation, etc.). As the current wrapper is already complex,
extracting the v2 part into its own directory allows for the v3 wrapper to
be written without breaking any existing tests or complicating the
existing code.

The current identified complexities that necessitate a thorough rework of
the existing v2 wrapper are:

 - Not all ports are discoverable in v3 (MST ports are not physical
   ports, but they can have EDID, be plugged, etc.), and they can change
   over time.
 - The v3 is unable to perform CRC computation, so many tests must be
   rewritten or adapted to work.
 - Not all ports can be plugged at once, which is a feature used by the
   existing v2 wrapper to set up the Chamelium.
