Set default Skia Gold session type

Sets the default session type for Skia Gold to be
OutputManagerlessSkiaGoldSession. This is what was being used by all
implementations except the Android instrumentation tests, so we are able
to remove some duplicate code and unnecessary child classes by setting
the default in the base implementation.
