Adding a speed feature for tx_size search

This patch factors out a function that computes the rd cost for
a given transform type given the transform partition already
computed. This is then used to develop a speed feature where the
transform size search disables trellis optimization but once the
transform sizes are decided, a final search is conducted with
optimization turned back on.
This patch does not change anything in speed 0 yet.
