Enable Java language level 9 by default.
This changes the default Java language level from 8 to 9, i.e. javac
invocations now use -source 1.9 -target 1.9.
The environment variable EXPERIMENTAL_JAVA_LANGUAGE_LEVEL_9=false is
added to switch back to the language level 8 behaviour. (Previously,
setting that variable to true was required to opt in to language level
9.)
Test: make droid java tests cts docs
Test: javap -v <some class file in output> | grep 'major version' (reports 53, for classes from 'benchmarks' which is in Android.bp and 'ahat' which is in Android.mk)
Test: make RunBluetoothRoboTests RunCarSettingsLibRoboTests (two main flavours of robolectric)
Test: make cts && cts-tradefed help
Test: atest CtsLibcoreTestCases (reasonably low-level device tests)
Test: atest CtsHostTzDataTests (arbitrary host test)
