Bug 1793560 - Remove navigate-to CSP directive r=tschuster

It has never shipped after being implemented years ago,
and was removed from spec in September 2022:
w3c/webappsec-csp#564

Now skipping navigate-to WPT tests. Filed issue for their future removal:
w3c/webappsec-csp#608

Also removed our own tests to ensure it is unimplemented.
