External Issue: Add LAPACK implementation for solve method in LinearAlgebra module

Summary of Problem

Currently, the LinearAlgebra package has a native solve() implementation to solve the linear system A * x = b but not a LAPACK implementation. It would be beneficial to support both an implementation that wraps the appropriate LAPACK routine and a native Chapel implementation.
