This unifies the codepath for high-bitdepth transforms and deletes
all calls to the old deprecated versions. This required reworking
the way 1d configurations are combined in order to support rectangular
transforms.
There is one remaining codepath that calls the deprecated 4x4 hbd
transform from encoder/encodemb.c. I need to take a closer look
at what is happening there and will leave that for a followup
since this change has already gotten so large.

1) Not every transform's internal signal is designed to fit in 16 bits.
2) If overflow happens in this function, it indicates that we need to
adjust the txfm's scaling. We shouldn't mute the overflow signal.
3) Saturation might be handy when all of our transform design are stable,
but I don't think we are at the stable point yet.
4) This will fix C/Trans16x16DCT.AccuracyCheck/1 failure in highbd mode.
