Blocks: Add support for variations in block.json` file

Browse Source 
We integrated variations with block types and the corresponding REST API endpoint in #52688. It's a follow-up patch to add missing support to the `block.json` metadata file when using `register_block_type`.

Some fields for variations are translatable.Therefore, i18n schema was copied over from Gutenberg: https://github.com/WordPress/gutenberg/blob/trunk/packages/blocks/src/api/i18n-block.json. The accompanying implementation was adapted as `translate_settings_using_i18n_schema`.

Props: gwwar, swissspidy, schlessera, jorgefilipecosta.
Fixes #53238.
