We currently pretend to be ready when using a placeholder
surface irrespective of whether the renderer is actually
ready to immediately render when a surface is attached.
This causes issues in two ways:
- Apps don't know when a player without a surface can be
connected to a surface and immediately start playing
- A paused player without a surface will use the 1 second
default doSomeWork loop, causing any pending decoding
to be extremely slow (see Issue: androidx/media#1973).
The fix is to let the placeholder surface case use the same
paths as the regular surface and with marking the first
frame as available as soon as the codec output buffer for it
is pending and ready for release.
