Remove old WebSourceBufferImpl::append()

Remove old WebSourceBufferImpl::append()

This is the third part of a three-sided MediaSource
Chromium/Blink+roll Blink/Chromium set of changes to enable
JavaScript web apps to continue to round-trip
SourceBuffer.timestampOffset set/get if SourceBuffer append
operations do not update the timestamp offset, and to
retrieve any updated timestamp offset as can occur during
upcoming "sequence" append mode compliant coded frame
processing.

This change removes the obsolete Chromium
WebSourceBufferImpl::append(,) now that Blink
WebSourceBuffer.h only has append(,,double*).

Please take a look. This depends on the first two parts landing first, and Blink
rolling after the second part:
Part 1=https://codereview.chromium.org/178153004/
Part 2=https://codereview.chromium.org/178763006/

Thanks!

PS2 has no change, just me fixing up my local git branches after the first CL
landed.

This is now only pending CR and the blink CL landing+blink roll
(https://codereview.chromium.org/178763006/).

PTAL.
