Evaluate xformOps at startTimeCode for static viewers

Browse Source 
Set env.timecode to startTimeCode (if authored) when converting Stage to
RenderScene. This ensures xformOps with TimeSamples are evaluated at the
initial pose for static viewers like materialx.js that don't support
animation playback.
