csputils: move image_params -> csp_params into a function

Although the line count increases, this is better for making sure
everything is handled consistently for all users of the mp_csp_params
stuff.

This also makes sure mp_csp_params is always initialized with
MP_CSP_PARAMS_DEFAULTS (for consistency).
