Compiler failed to synthesize Type[T] for local type alias T

[liufengyun]

Discovered in #6586, the following code fails to compile:

import scala.quoted._

inline def foo[T:Type]: Int = 10

def main = {
  type S = Int
  foo[S]                 // ok
  foo[Int]               // ok

  type T = Int => Int
  foo[T]                 // error
  foo[Int => Int]        // ok

  type U = List[Int]
  foo[U]                // error
  foo[List[Int]]        // ok

  type N = List
  foo[N]               // error
  foo[List]            // ok
}
