Update Android Gradle Plugin from 3.2.0 to 3.6.3

[thanwah]

Also updated the Gradle version to the minimum required (5.6.4).

Changes were made with the following commands: find . -name build.gradle -print0 | xargs -0 sed -i '' -e 's/3.1.0/3.6.3/g' find . -name gradle-wrapper.properties -print0 | xargs -0 sed -i '' -e 's/5.1.1/5.6.4/g'

Checked build speed by running "./gradlew build" in the directory "tests/cpp-empty-test/proj.android". After running gradlew once to download dependencies, build speed is unaffected: ./gradlew clean build Before (with AGP 3.2.0): BUILD SUCCESSFUL in 3m 52s After (with AGP 3.6.3): BUILD SUCCESSFUL in 3m 41s
