Multi window support for Android, iPad

Changed title to include iPad, which doesn’t support this feature either. (There was a request long ago that was mistakenly closed.)

[Feature] [iPad OS] Multiple Windows

Platform [X] iOS (iPad-specific) Obsidian Mobile version: v0.0.16 iPad supports multiple windows of a single app in various modes (standalone, slide-over, split view). Obsidian does not currently support this. With multi-window support, multiple Obsidian windows could be opened that each operate independently. This would enable multiple vaults to be opened simultaneously, for instance, or could also allow different files within the same vault to be opened at the same time.
