Block Editor: Remove repetitive calls to `file_get_contents()` in block editor settings.

The `get_default_block_editor_settings()` function used to repeatedly get the `default-editor-styles.css` file contents without any implementation to avoid this.

This commit utilizes a static variable to remove repetitive calls made during the same request. In tests ran on the front page of a site using Xdebug & Webgrind, the total `file_get_contents()` invocation count goes down from 181 to 93, and total self cost (the time that the function is responsible for) goes down from 160 ms to 93 ms.

Follow-up to [52042].
