feat: handle theme change based on preferences

[troZee]

Motivation

Closes #1597

Android 10 and iOS 13 added support for dark theme. User (like me ;p) can set dark theme as default theme. Application should adapt to this theme automatically, hence I would like to have automatically theme changing in my app, so I don't need to care about user preferences. This is only a draft, because RNP needs to be bumped to 0.62. Example will be add later, once expo adds support to 0.62.

Test plan

• Check, it theme changes based on user preferences (it should be done automatically)
• You cannot test it due above reasons. You can use my private fork to test it https://github.com/troZee/paperExample

Should I bump RN version to 0.62 in this PR ? Or should I wait for RNP with rn 0.62 ?
