Andreas Kling 7dda773426 AK: Add rvalue-ref qualifiers for Optional's value() and value_or() ...

This avoids a value copy when calling value() or value_or() on a
temporary Optional. This is very common when using the HashMap::get()
API like this:

    auto value = hash_map.get(key).value_or(fallback_value);
