    matrix: Add cogl_debug_matrix_print api
    
    As a convenience for debugging this adds a cogl_debug_matrix_print
    function that prints out the components of a matrix and any internal
    flags associated with the given matrix.
    
    (cherry picked from commit 3b33889ff1204f19347a9548320ba95baa54c18c)
