trmm: Triangular matrix multiply

Functions
template<typename scalar_t >
void	slate::tile::trmm (Side side, Diag diag, scalar_t alpha, Tile< scalar_t > const &A, Tile< scalar_t > &B)
	Triangular matrix-matrix multiply: \(B = \alpha op(A) B\) or \(B = \alpha B op(A)\) where \(A\) is triangular.
template<typename scalar_t >
void	slate::tile::trmm (Side side, Diag diag, scalar_t alpha, Tile< scalar_t > const &&A, Tile< scalar_t > &&B)
	Converts rvalue refs to lvalue refs.
