Stop posting video stats for every Render(); optimize storage.

There's really no reason for us to be posting this for every single
Render() call. They can be updated nearly as quickly during each
FrameReady() call. There's also no reason for us to create a new
PipelineStatistics structure every time either. Instead replace
a multitude of member variables with a PipelineStatistics member.

This is an optimization of PipelineStatistics usage so that we
can add a Decoder enum value later.

BUG= 793151 
TEST=existing tests pass.

commit c7d2a7d2291d41bf3b2bdb5b67bc2e733c9af6c7
Author: Dale Curtis <dalecurtis@chromium.org>

Add decoder name to PipelineStatistics; report to UKM.

There's value in tracking the decoder name along with the rest of
our WatchTime data, particularly LastPipelineStatus, for seeing
how a given decoder is performing in the field.

This adds the decoder name to the PipelineStatistics structure
and reports it up through the watch time reporter to the watch
time recorder. These end up reported as two new keys:

AudioDecoderName
VideoDecoderName

Since the decoder may change during playback due to errors or
configuration changes to unsupported content, we need to report
when fallback occurs. This is done by recreating the reporter
when a new decoder name is provided.

Decoder names are reported to UKM as zero valued enumerations;
the lists are as follows:

enum class AudioDecoderName : int {
  kUnknown = 0,  // Decoder name string is not recognized or n/a.
  kFFmpeg = 1,   // FFmpegAudioDecoder
  kMojo = 2,     // MojoAudioDecoder
};

enum class VideoDecoderName : int {
  kUnknown = 0,  // Decoder name string is not recognized or n/a.
  kGpu = 1,      // GpuVideoDecoder
  kFFmpeg = 2,   // FFmpegVideoDecoder
  kVpx = 3,      // VpxVideoDecoder
  kAom = 4,      // AomVideoDecoder
  kMojo = 5,     // MojoVideoDecoder
};

BUG= 793151 
TEST=updated unitests, manual verification

Add decrypting a/v decoder names to UKM reporting.

http://crrev.com/528719 forgot to include the CDM wrapper decoders:
DecryptingAudioDecoder and DecryptingVideoDecoder. These will now
have enum values of 3 and 6 respectively.

BUG= 793151 
TEST=no more unknown decoder warning for Netflix.
