[css-color-hdr] New values for dynamic-range-limit property #11698

The current draft https://drafts.csswg.org/css-color-hdr/#the-dynamic-range-limit-property suggests the following values for this property:

standard | high | constrained-high | <dynamic-range-limit-mix()>

With the suffix limit at the end of the name, these values can be a little confusing.

1. Does the value high mean the dynamic-range is high?
2. Or does high mean the limit on the dynamic-range is high?

These options are proposed in the F2F meeting and here #11558 (comment) as well.

1. none, constrained, standard
2. no-limit, constrained, limit-to-standard
3. no-limit, limited, limit-to-standard
