Remove PrintParams object.

The only way to theoretically get one is via doc.getPrintParams(),
and it always returns in error.

Even if one were returend to JS, there aren't any methods/callbacks
to change its properties.

Even if there were methods to change its properties, the information
it stores doesn't align with what is in the JS spec for this object.

Even if it were aligned with the JS spec, the way we check for its
presence as the ninth parameter in CJS_Document::print() doesn't
match the way its use is documented in the spec as the sole
first parameter.

Instead implement the older, simpler behaviour as spec'd prior to
6.0, and toss this enhancement altogether.

Move function to check the result of ExpandKeywordParams() to
js_define.h so other files can use it. Update comment in that
file to remove reference to deprecated enum.

Expand test for API and introduce callback to log parameters.
