JS 'let' and 'const' error out in inline components

      Description

      There seems to be an issue with inline components and the more recently supported JS declarations:

      import QtQuick 2.15
      
      Item {
        component Test: QtObject {
          function a() { var v = 1; console.log(v) } // works as expected
          function b() { let v = 1; console.log(v) } // Identifier v has already been declared
          function c() { const v = 1; console.log(v) } // Identifier v has already been declared
        }
      
        Test {id: t}
      
        Component.onCompleted: { 
          t.a(); t.b(); t.c()
        }
      }
      
      

      var is ok, but let and const result in a false positive parsing error, thus the qml code fails to load.
