fix(Android): fix build deprecations (#2116)

## Description

This PR intents to fix some "Deprecated in Java" warnings when building
on android. I decided not to suppress warnings manually when it is
inescapable to avoid the warning.

Fixes #2018 

## Changes

- replaced deprecated targetElavation with elevation
- adjusted usage of porter duff color filter
- calculating header top inset using recent method if android API >= 30
(the warning persists as the previous APIs still require deprecated
method)
- fixed guarded runnable deprecated warning
- removed unused import

```

## Test code and steps to reproduce

- build android app to compare deprecation warnings quantity
- run the example app and see wether the header shadow, backButton color
and top inset behave correctly

## Checklist

- [ ] Ensured that CI passes
