Cannot access Block, Field UI, Views UI config pages when Config Enforce Devel is enabled

Adding these two lines to config_enforce_devel_config_enforce_form_denylist works around the problem. Not ideal, but here's a patch to get around the issue.

    'block_admin_display_form',
    'block_form',

Changing the title to reflect the more widespread set of errors. Also upping the priority because this is completely breaking things.

As far as I can tell, this change was probably introduced as part of #config_target in ConfigFormBase: using validation constraints for editing simple config → . After some tinkering, I think the fact that we're extending ConfigFormBase for the embedded enforce form is the root cause that's causing Drupal core to attempt to call that method that's in the fatal error; basically, since the embedded enforce form now looks like a config form, it's making Drupal core treat the parent form - e.g. the block layout form, field UI, etc. - as ConfigFormBase even though they themselves only extend FormBase.
