CLDR-15972

There are multiple fixes for the larger numbers for Catalan. These changes also include the addition of the plural ordinal rules for both masculine and feminine, and fix roundtrip parsing of digit ordinals.

These changes were tested with the Number Format Tester.

I don't feel competent reviewing RBNF changes. Added @richgillam as a reviewer...

I'm actually queueing up several pull requests for RBNF this week. I plan on asking someone to review these pull requests once these are in good shape. It's tedious to ask for CLDR-TC approval and a reviewer separately for each issue and pull request. It would be easier to do it all in bulk. Some of these fixes are 1 line changes. Though if someone wants to preemptively assign each issue to me and approve the pull requests, that's fine too.

All changes have been verified to parse and roundtrip with Number Format Tester, and that the new observed behavior matches the desired requested change.

I can't speak to the actual linguistic content, but the changes look plausible and syntactically everything looks fine.
