Message:

Editor: Improve frontend performance for get_default_block_editor_settings().

The wp_max_upload_size() function can be expensive to call, especially for large sites or multisites. For the frontend usage of get_default_block_editor_settings() knowing the allowed upload size is typically unnecessary.

This changeset adds a condition so that wp_max_upload_size() is only called if the current user can actually upload_files. It keeps the data present when it is actually needed while avoiding the execution overhead when it is not needed.

Props janthiel, Clorith, flixos90, spacedmonkey.
Merges [54769] to the 6.1 branch.
Fixes #56815.
