LibWeb: Make getElementsByClassName() case-insensitive in quirks mode

Browse source 
From https://dom.spec.whatwg.org/#concept-getelementsbyclassname:

    The comparisons for the classes must be done in an ASCII case-
    insensitive manner if root’s node document’s mode is "quirks", and
    in an identical to manner otherwise.
