Ability to opt out of "Content Block" restrictions [Performance degradation]

Problem/Motivation

When working on a site with a large amount of Blocks, this module can cause PHP memory limits to be hit when trying to visit the manage display page with Layout Builder enabled.

I've asked a couple of other developers (colleagues) and they seem to experience the same.

Steps to reproduce

Have a large amount of blocks
Try to visit the manage display page of a content type where Layout Builder is enabled.

Root cause

This performance problem is due to the number of options that the interface has to *render* (in contrast to business logic or database calls). Specifically, it has to render a checkbox element for each of the blocks in the system *twice*, once for the allow-list restrictions, and once for the deny-list restrictions.

Proposed resolution

1. Add a setting for this module that allows sites to suppress "Custom blocks" from being restricted via the UI.
2. Point to our existing documentation ( https://www.drupal.org/docs/contributed-modules/layout-builder-restricti → ...) that explains how sites can programmatically set restrictions for individual custom blocks.

Rationale: although this seems like a sacrifice, I speculate that the types of sites that experience this performance problem (i.e., one with thousands of reusable blocks) likely don't want content editors to have a list of those thousands of reusable blocks to be place-able via Layout Builder. So maybe this option wouldn't negatively affect them.

Hello,

I face an out of memory, maybe because of custom block, for all content type managed with the layout builder I have this error on path "/admin/structure/types/manage/-content_type-/display"

The out of memory is cleared ad soon as I uninstall the layout_builder_restriction module.
I have not yet isolate the root cause of this.

Regards,

Found the origin of the out of memory in layout builder module, refer issue 3354180 : Memory timeout on "manage display" page for contents with layout builder. 🐛 Memory timeout on "manage display" page for contents with layout builder. Postponed: needs info
