Unable to use same ResultType as StreamingResult in more than one method.

[shivuslr41]

If I use same ResultType as StreamingResult in more than one method, NewResultTypeView(v) accepts only single MethodResponse type that is generated for the first declared method in DSL.

simple repro:

package design

import (
	. "goa.design/goa/v3/dsl"
)

var _ = API("streamer", func() {
	Server("Streamer", func() {
		Services("Streamer")
	})
})

var _ = Service("Streamer", func() {
	Method("subscribe", func() {
		Payload(func() {
			Field(1, "eventId", Int64, func() {
				Example(101)
			})
		})
		StreamingResult(Event)
		GRPC(func() {
			Response(CodeOK)
		})
	})

	Method("resume", func() {
		Payload(func() {
			Field(1, "eventId", Int64, func() {
				Example(101)
			})
		})
		StreamingResult(Event)
		GRPC(func() {
			Response(CodeOK)
		})
	})
})

var Event = ResultType("Event", func() {
	Field(1, "message", String, "Message sent to the server")
	Field(2, "action", String, func() {
		Enum("added")
	})
	Field(3, "added_at", String, "Time at which the message was added", func() {
		Format(FormatDateTime)
	})
	Required("message", "action", "added_at")
})

• go version: go version go1.18.7 linux/amd64
• goa version: Goa version v3.10.1

Compile error can be found in generated file at -> gen/grpc/streamer/client/client.go

Maybe related to this issue/fix: #2723
