Subject: [PATCH] Theme Editor: Disable CodeMirror CSS linting.

Being a good idea in theory, in practice it does not always work reliably, may not recognize newer CSS properties, and sometimes displays phantom errors with no particular error message.

A plugin can re-enable CSS linting via the `wp_code_editor_settings` filter.

Fixes #44471.
