Date: merge 6.4 and 6.5 compat files

[ramonjd]

Resolves #58431

What and how?

This commit merges the 6.4 and 6.5 compat changes for gutenberg_update_wp_date_settings(), and stores them in a single place in compat/6.5.

6.4 compat changes (already merged to Core for 6.4)

• Date: add relative time translations for moment.js #53931
• Script loader 6.4 compat: check for init hook completion #58406

6.5 compat changes (needs backporting for 6.5)

• Add a timezone offset value for display purposes #56682

Why?

Compat code consolidation and to avoid duplicate filters.

Testing Instructions

Fire up this branch and open the editor.

In the browser console, run wp.date.getSettings().

Check that properties exist for:

1. timezone.offsetFormatted exists
2. l10n.relative.* exists

Smoke test functionality.

1. Follow test instructions in Timezone displays offset with decimals instead of minutes #56254 to see timezone offset
2. Run wp.date.humanTimeDiff( new Date() ) in the console. You should see a relative translation "a second ago"

Thanks @getdave

This PR doesn't need a backport. It's just a bit of cleaning up.

@afercia already has a patch for the 6.5 changes added to Gutenberg in #56682

See: https://core.trac.wordpress.org/ticket/60105
