[Feature Request] Add widgets to view notes on home screen.

[rajan-31]

• A widget which can show a note on the home screen (not the list of notes, the actual content of a note)
• Edit the note by clicking it
• Customizable background, transparent (with colors), etc.

Thanks for requesting this. A homescreen widget is something I've been wanting to get into the app for quite some time now, and with the ongoing app rewrite using Compose, I am wanting to look into Jetpack Glance for implementing homescreen widgets soon.
