brandtr 0b8bfb9d98 Reuse allocated encoders in SimulcastEncoderAdapter.
Prior to this change, the SimulcastEncoderAdapter would destroy and create
encoders whenever it is being reinitialized. After this change, the
SimulcastEncoderAdapter will cache the already allocated encoders, and reuse
them after reinitialization.

This change will help in reducing the number of PictureID "jumps" that have
been seen around encoder reinitialization.

TESTED=AppRTCMobile, Chrome desktop, and internal app, with forced encoder reinits every 30 frames and https://codereview.webrtc.org/2833493003/ applied.
