gdbus-codegen: Generate signal marshallers for each interface signal

Browse Source 
We relied on g_cclosure_marshal_generic() to easily generate signal
marshallers, but this relies on inspecting each parameter type with ffi
and this implies a performance hit, other than breaking the stack-frame
unwinder used by Linux perf and so by sysprof.

Given that we know the types we work on, it's easy enough to generate
the marshallers ourself.
