Improve plugin performance on the Mac
This makes a few changes:
- Switch to memcpy instead of CG drawing to copy pixels from the transport bitmap to the backing bitmap (this is a substantial perf win).
- Send transparancy information to the WebPluginDelegate, since it's no longer equivalent to not having a background DIB on the Mac (and likely on the other platforms in the future).
- Don't clear the transport DIB for non-transparent plugins, since they will be drawing over whatever is there anyway.
BUG=41340
TEST=Both transparent and non-transparent plugins should continue to draw correctly. Framerates for large CG plugins (e.g., in-window Netflix streaming) should be higher.
