Issue description

(I believe this is a duplicate of #92262, but there wasn't much of an MRP provided in that issue.)

When a project includes a "CSV Translation" file, that file will emit .translation files (one for every language/locale) next to the .csv file. The writing of these .translation files will (in the same callstack) seemingly cause every scene in the project to be loaded, which in turn will try to load every resource referenced by those scenes, most of which will (on initial import) fail, since many of these resources won't have been imported at that point.

The type of resource matters to some degree, due to the ordering of the reimports that happens here:

... as this will sort the imports by the importer name (ResourceImporter::get_importer_name()), where "csv_importer" will often get sorted first, before things like "texture", like in the provided MRP.

Here is the callstack when one of these texture resources fail to load due to not having been imported:

(Note that I disabled import/use_multiple_threads in the MRP to make debugging more straight-forward, hence the callstack, but that setting is inconsequential to this issue.)

As far as I can tell (after bisecting) this is a regression in 4.3, caused by #60965, as EditorFileSystem::_update_pending_scene_groups loading all the scenes in EditorFileSystem::_process_update_pending is largely what's causing this problem.

However, it does seem to me like the CSV importer itself is also part of the problem here, as every other import artifact that triggers EditorNode::_resource_saved will simply early out in EditorFileSystem::_find_file here due to those import artifacts being in the .godot folder, as opposed to being generated next to the source file like with .csv files.

Steps to reproduce

1. Ensure there is no existing .godot folder in the MRP
2. Open the MRP in the editor
3. Note errors about failing to open/load logo1.png, logo2.png and their respective import artifacts
4. Close the project
5. Open the project again
6. Note the lack of errors
