rtc: Add optimized scaler for 2:1 horiz only for Bilinear

For x86 only.

This also fixes a bug with the aom_scaled_2d(),
for horiz or vert only scaling. The x/y_q4 was not set to 0
if the height/width is the same (no scale change).
So for 2:1 horiz scaling, it was still filtering along
the vertical direction.

Eightap case to be added, and ARM to be added.
