Revert "Store a raw_packetization bool in RtpSenderVideo rather than inferring"

This reverts commit fc1cbcf05221bf26b6fa94ecb018a5225060ddb4.

Reason for revert: Reverting while we figure out why the check is triggering downstream

Original change's description:
> Store a raw_packetization bool in RtpSenderVideo rather than inferring
>
> Ensure all calls to SendVideo() use a raw packetizer when they should
> rather than inferring it from the absence of |codec_type| - an issue
> when the caller doesn't know the correct packetization (eg
> RTPSenderVideoFrameTransformerDelegate).
