Cannot go to definition of an annotation of a type

[nicolasstucki]

This can be reproduced in dotty.tools.languageserver.DefinitionTest with

@Test def i4678: Unit = {
    code"""class Foo {
          |  val x: Int = (1: @annot${m1}1${m2} ${m3}@annot2${m4})
          |}
          |class ${m5}annot1${m6} extends scala.annotation.Annotation
          |class ${m7}annot2${m8} extends scala.annotation.Annotation
          |""".withSource
      .definition(m1 to m2, List(m5 to m6))
      .definition(m3 to m3, List(m7 to m8))
  }

When looking for a tree that is in a position inside a TypeTree we also need to check the type for its annotations. Each annotation has the tree and its position.
