Create an Alias for use in as a multi return type

[ChrisKader]

Currently if we have multiple functions that return the same multiple returns, we have to define those returns individually.

---@return number x, number y, number z
GetPosition = function()
    return 1, 2, 3
end

We are able to create aliases for table values.

---@alias Position {x: number, y: number, z: number}

---@return Position[]
GetPositions = function()
return {{x = 1, y = 2, z = 3},{x = 1, y = 2, z = 3},{x = 1, y = 2, z = 3},{x = 1, y = 2, z = 3}}
end

It would be helpful if we could create an alias that would allow for us to have a single return type for functions that have the same multi return types.

---@alias Position x: number, y: number, z: number

---@return Position
GetPosition = function()
    return 1, 2, 3
end

Agree. The need for this was raised with regards to function params in #1772, but the same concept applies for return values IMO. I'd love it if there were a tuple type so that function params/returns could be reused.
