Disambiguate the 'List view' terminology

[afercia]

Description

Splitting this out from #61535

The editor has a 'List View' feature to show and navigate the hierarchy of blocks.

Some blocks do have a 'List view' setting to display their content in a list, as opposed to a 'Grid view'. See for example the Latest Posts, RSS, and Post Template bocks.

As such, the editor UI uses the terminology 'list view' for very different features. While this may not a big problem for sighted users, it is very confusing for blind users, users with cognitive impairments, low tech-savvy users etc.

Features in software should use unambiguous names to avoid any potential confusion.

Step-by-step reproduction instructions

• Add a Latest Posts, an RSS, and a Query Loop block (note: the Query Loop block contains a Post Template block).
• Observe all the three blocks do have two buttons in their block toolbar to set the block content to 'List view' or 'Grid view'.
• Observe the 'List view' name is used also for the List View in the Document Overview.

Additiobnally, the ambigous string may be confusing for translators as well. A few examples:

In Spanish it's 'Vista de lista' for both features:

In German it's 'Listenansicht' for both features:

In Italian it's 'Vista elenco' and 'Visualizzazione in modalità elenco':

Good issue. I'd appreciate verbiage suggestions. I've shuffled some labels around to account for that.

I wonder whether 'List View' is the best name for the feature that shows and allows to navigate the hierarchy of blocks in the first place.

Anecdotally, every time I have conversations with users, we commonly refer to this feature as 'the list of blocks'.

Does the term 'view' in 'List view' helps users in any way? Is it really a 'view'? I'm not sure this can be called a 'view'. To me, it's a list of the objects in the content that shows their hierarchy and nesting, and it allows to navigate and select them.

It's a list, why not call it 'Blocks List'? Yes, there are 'Patterns' as well, but after all they're a collection of blocks.
