  [MSE] Reset extra memory cost inside removedFromMediaSource()

Reviewed by Xabier Rodriguez-Calvar.

When the SourceBuffer is removed from a MediaSource, its TrackBuffers are cleared (and so is
its data, which can take a good amount of memory), but the SourceBuffer still accounts for
the cost of its old data, as m_extraMemoryCost isn't reset to zero.

See: https://github.com/WebPlatformForEmbedded/WPEWebKit/pull/1264

This patch resets m_extraMemoryCost when the SourceBuffer is removed.
