Application should start in safe mode after a crash

For example if this note is loaded:

https://github.com/laurent22/joplin/files/12407306/bloated.note.-.inline.jex.zip

It is going to freeze the application as CodeMirror parses the large Base64 image. If the user force quit the application, and reopen it, it will freeze again because the same note will still be open.

We should do two things:

• After a crash or force-quit, the app should start in safe mode

• In safe mode, the app should load the note in a simple textarea component. The other editors should not load. We have a packages/app-desktop/gui/NoteEditor/NoteBody/PlainEditor/PlainEditor_tsx.txt which renders a plain text editor, which perhaps can be used for this. It used to work but it was a long time ago.

It was also suggest to start the app with no notes being selected but the problem is that as soon as the user switches to a notebook a note will be automatically selected, which may crash the app again.
