This PR fix fn return alias of fixed array.

• Don't change return type from alias type to fixed array type in parser chase.
• Fmt is correct.
• Change the related tests.

type Mat = [2][2]int

fn main() {
	a := Mat([[1, 2]!, [3, 4]!]!)
	println(a.foo())
	z := a.foo()
	assert z == [[1, 2]!, [3, 4]!]!
}

fn (v Mat) foo() Mat {
	return v
}

fn bar() Mat {
	return Mat([[1, 2]!, [3, 4]!]!)
}

PS D:\Test\v\tt1> v run .
Mat([[1, 2], [3, 4]])

Fmt is correct.
