Block Editor Tools: Add A List View Option to PostPicker

[kevinfodness]

Description

WordPress 6.7 is introducing DataViews as a new way of presenting a list of items that can be optionally searched and filtered. We should add an option to the PostPicker to allow it to display using a "list" view type instead of the default modal. The modal should continue to be the default for this new option. Implementers can decide to opt in to using the list view powered by DataViews for a more compact selection experience.

This work will not be actionable without testing on a beta or released version of 6.7.

Use Case

When a user wants to implement a more compact post selection interface, they should be able to do so using a list view powered by DataViews.
