[Why]
kms_chamelium tests file has grown so much and became a bit big to
manage.
Splitting specific tests like we do for kms_ tests into separate files
puts logically related functionalities into the same place so tests are
more clear.

[How]
Split kms_chamelium into 4 different tests, each testing something
specific. The tests are:
1. kms_chamelium_audio
2. kms_chamelium_edid
3. kms_chamelium_frames
4. kms_chamelium_hpd
5. kms_chamelium_color which used to be kms_color_chamelium but renamed
   for consistency.

All common code lives in kms_chamelium_helper and the function names
have a chamelium_ prefix.
