Message:

Blocks: Add new render property in block.json for block types

New render field in block.json file that accepts a string value. It allows to pass a path to the PHP file that is going to be used to render the block on the server. Related PR in Gutenberg: ​https://github.com/WordPress/gutenberg/pull/42430.

Props spacedmonkey, luisherranz, welcher, noisysocks, matveb, fabiankaegy, aristath, zieladam.
Fixes #53148.
