Clean up script-tests in css3/filters

Clean up script-tests in css3/filters

Rewrite the parsing tests using
css-parser/resources/property-parsing-test.js and also use testharness
for the computed style test.

Drop css3/filters/filter-property.html since that is already covered by
the wider parsing tests. Also remove the template html file and inline
the scripts for effect-reference-reset-style-delete-crash.html [1] and
effect-reference-delete-crash.html, clearing out the script-tests sub-
directory.

[1] This test was actually referencing the
    effect-reference-delete-crash.js file, meaning it was a duplicate.
