Currently CI runs gradlew lint for android projects using build-fat-aar which is not needed now that we can run lint from root project. Current setup also doesn't update mozlint.json so phabricator doesn't recognize the lint failures. This bug adds gradlew lint to mach lint through the android-{fenix|focus|ac} linters in addition of ktlint and detekt which were added in D216999
This patch changes android lint configuration to generate JSON report of errors and then reads these errors in lints.py to report in the same format as other linters.
Creating new treeherder task for each of `android-{fenix|focus|ac}` linter as android-fenix can take up to 20 minutes ot run now with the addition of gradlew lint, which is almost the same as the existing mozlint-android-lints task takes, so doing this in parallel will be nice.
Follow up work would include removing all the original detekt, ktlint and lint tasks from treeherder which will make creating these new tasks more justified.
