LibWeb: Relax HTML parser to allow more tags inside <select>

Browse source 
This implements parsing part of customizable <select> spec update.
See whatwg/html PR #10548.

Two failing subtests in `html5lib_innerHTML_tests_innerHTML_1.html`
and `customizable-select/select-parsing.html` are due to the spec
still disallowing `<input>` inside `<select>`, even though Chrome
has already implemented this behavoir (see whatwg/html#11288).
