Delete gpu/command_buffer/common/logging.h

command_buffer was historically included in nacl-compiled things, and base
wasn't. These days, base is included in nacl-compiled things too, so the
duplication can be removed.

This will remove 1 static initializer.

Don't enumerate audio and video input devices on startup on Mac.

This change fixes a regression in startup latency on Mac.  (It also avoids
reintroducing a minor enumeration bug, by setting the initial counts
to an invalid value instead of zero.)
