Under memory pressure, we should actively evict content in ManagedMediaSource and and ManagedSourceBuffer. Unlike a MediaSource which can only evict content in the coded frame eviction [1] algorithm during the prepare append algorithm [2]; a ManagedMediaSource and its ManagedSourceBuffers can evict content at any time, after which an "buffered change" event will be fired on the SourceBuffers [1] https://w3c.github.io/media-source/#dfn-coded-frame-eviction [2] https://w3c.github.io/media-source/#sourcebuffer-prepare-append
