Newly created media type doesn't have default entity view mode configuration

Verified this is an issue even with MR113.... Will commit that MR and work on the fix here though. Not sure why, since we now hook into entity_view_display's presave hook.

The issue is due to the default media source plugin field being returned and not created during Media Type creation.

@japerry - do you suggest we create the default view mode on hook_ENTITY_TYPE_insert()?

No because other things, like config imports would hit hook_insert, causing unintended issues.

The core issue is here:
https://git.drupalcode.org/project/drupal/-/blob/11.x/core/modules/media...

The problem is that we already have a defined field for the source plugin, so this will never be null. Instead, we could look at doing what media library does, hooking into the the submit handler for entity type creation. When creating a new media type via config, its assumed they have a corresponding view config, we don't want to auto create it there.

See https://git.drupalcode.org/project/drupal/-/blob/11.x/core/modules/media...

With our config, we want to ensure only the embed code or download/sync field appear in the view display. If helper methods are needed, use AssetMediaSourceManager to store those methods.

Pipeline is now passing, hence moving ahead for review.
