CM updates

[UjinT34]

Describe your PR, what does it fix/add?

• Sets default SDR to gamma22 since most clients and hw use it with sRGB. render:cm_sdr_eotf = 3 to use sRGB TF.
• Marks WP_COLOR_MANAGER_V1_FEATURE_SET_MASTERING_DISPLAY_PRIMARIES and WP_COLOR_MANAGER_V1_FEATURE_EXTENDED_TARGET_VOLUME. This support isn't fully correct, mastering primaries should be used to determine color range for tonemapping and dealing with values outside 0.0 - 1.0 range. Should make gamescope and some other clients happier.
• Removes xx-cm and frog-cm because they aren't supported, have some HDR hacks that will mess with SDR. Some clients prefer those protos over wp-cm and hit some bugs.
• Makes primaries and image descriptions immutable to improve their id generation and conversion caching.

Is there anything you want to mention? (unchecked code, possible bugs, found problems, breaking compatibility, etc.)

Will make some colors look different by default. Border shader might need a revert or a TF parameter.

Is it ready for merging, or does it need work?

Ready

border shader should be treated as srgb, no? Why would th ecolors shift?

Should there be a difference between render:cm_sdr_eotf = 0 and render:cm_sdr_eotf = 1 with these changes?

0 means default which might be changed in the future

It uses sRGB TF on main and gamma22 with this PR. It's not clear which TF should be used. Looks like a lot of real-world stuff assumes sRGB colorspace with gamma22 TF or even mislabels gamma22 TF as an sRGB TF.

Is it expected to fail?
