Feature #21813: Add [:forward, :...] symbol tuple to indicate forwarding arguments when calling `Method#parameters`

When accessing Method#parameters for a method using forwarding parameters, an unexpected behavior arises:

def foo(*, **, &)
  "puts(#{(method(__method__).parameters.dig(0,1))})" # Works fine
end


def foo(...)
  "puts(#{(method(__method__).parameters.dig(0,1))})" # Fails!
end

It's very strange that you can't access the parameters, on eval, using the symbols provided at Method#parameters.

Adding [:forward, :...] or [:forwarding, :...] for those cases feels simply natural.
