feat: switch ktlint for spotless

[kacperkapusciak]

Description

Using ktlint directly as gradle task is very powerful and flexible but due to problems (#1085, #1090) we've decided to use formatting/linting framework - Spotless.

PR based on expo/expo#12545

For formatting per file -PspotlessIdeHook flag is used

The Spotless plugin for Gradle accepts a command-line argument -PspotlessIdeHook=${ABSOLUTE_PATH_TO_FILE}. In this mode, spotlessCheck is disabled, and spotlessApply will apply only to that one file.

As stated above, Spotless doesn't support linting per file. It makes it impossible to use spotlessCheck with lint-staged. Formatting per file with spotlessApply works fine.

Fixes #1090
Fixes #1085

Changes

• Use ktlint within spotless plugin
• Adjust format-android.js script
• Remove lint-android.js script

Checklist

• Ensured that CI passes
