HTMLFormElement should use WeakPtr to keep track of its FormNamedItem
https://bugs.webkit.org/show_bug.cgi?id=209925

Reviewed by Wenson Hsieh.

Like r259393, this patch replaces the HashMap of AtomString to the raw pointer of a FormNamedItem
by a HashMap of AtomString to WeakPtr of a FormNamedItem.

It also replaces a bunch of ASSERT_WITH_SECURITY_IMPLICATIONs with ASSERTs since there are no more
security implications left after this patch.
