contain-intrinsic-size - improve docs

[hamishwillee]

contain-intrinsic-size docs are incomplete and inaccurate.

More work to be done:

• Need to update https://github.com/mdn/data/blob/main/css/properties.json
• Need docs for
  • contain-intrinsic-width
  • contain-intrinsic-height
• Perhaps some examples
• Update CSS containment with
  • Information about contains-intrinsic-size in the appropriate section on size containment.
  • information about content-visibility as this also triggers CSS containment.

This is related to #20876

Can we ease the reading level down? i.e. intrinsic, mitigated, and computational may not be understood by native English speakers and we have a large ESL audience.

https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Containment mentions:

The specification defines a single CSS property contain ....

we should likely add this to that page.

Thanks all. I'm going to merge this in the current state 👍🏻 it looks like we can revisit the auto value if there's an outcome from the separate discussion on the benefits there :)
