Integration tests for 16kb dev option

Adding tests to verify end to end functionality for dev options. This test verifies - /data reformatting to ext4 - switching to 16kb kernel - switching back to 4kb kernel - Persistent notifications in page-agnostic mode - Disabling developer option in page-agnostic mode Test: m Enable16KbTest && atest -c Enable16KbTest Bug: 341995374 Change-Id: Ieaa149831b5205a15b259982f0349dc94d4fae92
