CWG-D009: ADST types replacement

Replace the ADST forward and inverse functions:
- 4-point: DST-4 using butterfly operations.
- 8-point: Graph Fourier Transform with self-loop of 1.5
           using matrix multiplication.
- 16-point: DST-7 using matrix multiplication.

The scaling for the inverse matrix multiplication is 7.
The scaling for the forward matrix multiplication is 12.
