commit-bot@chromium.org a095041f51 Remove SkRecorder's kWriteOnly mode.
I'm soon going to have SkRecorder start calling getTotalMatrix(), which
would be broken in write-only mode.  That change is big and nebulous,
but it's clear kWriteOnly needs to go, so we might as well kill it now.

My notes in bench_playback about kWriteOnly mode being important were
probably overly cautious.  I now think this is a fair enough comparison
even re-recording into a read-write canvas.
