Blocks: Parse the arguments earlier in register_block_type_from_metadata().

Browse Source 
This makes it possible to register a block by passing an array of arguments, without the presence of a `block.json` file.

Follow-up to [48141], [49948].

Props aristath, spacedmonkey, mukesh27, costdev, audrasjb, oglekler, felipeelia, hellofromTonya.
Fixes #56865.
