  [WK2] Add ArgumentCoder<std::unique_ptr<T>> specialization
https://bugs.webkit.org/show_bug.cgi?id=249022

Reviewed by Kimmo Kinnunen.

Add the ArgumentCoder<std::unique_ptr<T>> specialization, supporting
encoding and decoding such objects. The logic follows similar
specializations like the ones for std::optional<T> or RefPtr<T>.

This can be used to replace std::unique_ptr<T> special-casing in the
generate-serializers.py script, since the logic of encoding and decoding
is identical.

The testing baseline for the generated serializers code is updated. Test
cases covering std::unique_ptr<T> variants in ArgumentCoderTests suite
are added.
