Support type aliases (#1404)
* add a simple positive test

* add lambda expressions to microjuvix language

* add basic normalization of type aliases

* fix test name

* normalize only functions on types

* normalize when matching

* fix type of inductive names

* improve detection of normalizing functions

* remove obsolete comment

* match constructor return type

* add test for issue 1333

* fix existing tests

* use lambda case

* add strong normalization

* Add test cases for type aliases and another fix
