[WIP] Patterns: Investigate using block name to name override attributes

[glendaviesnz]

What?

This is just a quick test to see how things look/work if we use only the block name as the override attribute identifier

Why?

Why not :-)

How?

Changes the attribute meta field from id to name

Testing Instructions

• Add a synced pattern and set some pattern overrides. Make sure you set a block name for each of the overridden blocks - currently there is no UX to warn of the need for this
• Add an instance of the pattern to a post and override the content and make sure it saves in the pattern attributes under the block name
• Check the overridden content displays in the frontend.

Using just the block name opens up the possibility of easily switching patterns that have blocks with the same names and having the content copy over, but it also opens the possibility of users inadvertently adding blocks with the same name within a pattern and having content overwritten by mistake:
