Recover tile coding performance

After porting tile coding from VP9 to VP10, some performance
degradation was seen because of the difference between VP9 and
Vp10 baseline. This patch disabled some features in VP10 while
tile coding is turned on. Also, an encoder control API was added
back for this use case.
