clutter_primaries_to_wayland made sense when there only existed
ClutterColorspace. Now that ClutterPrimaries also exist, it makes more
sense to change that func to clutter_colorspace_to_wayland.

This TF can't be defined as a TransferFunction enum because it needs a
gamma_exp value too.
Add to EOTFType enum a new type: EOTF_TYPE_GAMMA.
With this new type, now EOTFs are unions that can have either
a TransferFunction enum or a gamma_exp.
Set gamma_exp as uniform.
Add the support of it in the color management protocol.

These properties now are tagged unions:
- ClutterColorimetry:
Can be from colorspace or primaries;
- ClutterEOTF:
Can be from known tf or custom gamma exp (next commit);
- ClutterLuminance:
Can be defined explicitly or derived;
Make the color management protocol use them too.

meta_wayland_color_management_dispose func is only called when the compositor
is shutting down, in that case the wl_globals are already automatically removed.
meta_wayland_color_management_dispose calls wl_global_remove again,
this makes a SIGSEGV when color_management is enabled and mutter is being
shut down.
Stop calling wl_global_remove to fix it.

When a surface is destroyed, the existing feedback surfaces are marked
as inert by setting the wl_resource user_data to NULL. This wasn't
handled in the feedback surface destructor.

Hooks up the wayland protocol to the color state luminances. The color
state handles the default levels so we can just pass everything through
after we checked for all the error conditions.

To expose it, run mutter/gnome-shell with `--debug-control` and then call
`./tools/debug-control.py --enable ColorManagementProtocol`, or set
`MUTTER_DEBUG_COLOR_MANAGEMENT_PROTOCOL=1`.
