Rewrites for triangular matrices

[tanish1729]

Description

Currently, we check for triangular matrices by seeing whether it is an output of a cholesky Op or not. It can then be used to add optimized rewrites for the triangular matrices.

1. det(triangular) -> product of diagonal elements
2. inv(triangular) -> use solve triangular
