  [WK2][GLib] Add ArgumentCoder<GRefPtr<GUnixFDList>> specialization
https://bugs.webkit.org/show_bug.cgi?id=247522

Reviewed by Michael Catanzaro.

Move encoding and decoding logic for GUnixFDList objects into a separate
ArgumentCoder specialization, removing the logic from the UserMessage
class's encoding and decoding methods.

Nullness of a GRefPtr<GUnixFDList> is preserved, and a file descriptor
leak during decoding is fixed. When encoding, the gathered UnixFileDescriptor
objects should be moved through the encoder to avoid further duplication,
but this will only work later once other specific ArgumentCoder specializations
properly handle rvalues.
