Triangular Solver with multiple right-hand sides (TRTRS)

This function solves a system of linear equation with triangular coefficient matrix along with multiple right-hand side vector

$$Ax=B$$

where $A$ is a dense lower or upper triangular matrix of size $m \times m$, $x$ is a vector need to be computed, and $B$ is input vector. The maximum matrix size supported in FPGA is templated by NMAX.
