LibJS+LibWeb: Convert string view PrimitiveString instances to String

Browse source 
First, this adds an overload of PrimitiveString::create for StringView.
This overload will throw an OOM completion if creating a String fails.
This is not only a bit more convenient, but it also ensures at compile
time that all PrimitiveString::create(string_view) invocations will be
handled as String and OOM-aware.

Next, this wraps all invocations to PrimitiveString::create(string_view)
with MUST_OR_THROW_OOM.

A small PrimitiveString::create(DeprecatedFlyString) overload also had
to be added to disambiguate between the StringView and DeprecatedString
overloads.
