Fix the KCL any type and array coercion incorrectly nesting (#6816)

* Add sim test for any type

* Fix doc comments to match code

* Add array ascription tests

* Commit new test output

* Fix to not panic when type is undefined

* Fix to not panic on use of the any type

* Update test and generated output

* Fix error message after rebase

* Fix subtype of any

* Fix KCL to use new keyword args

* Fix to not nest MixedArray in HomArray

* Update output

* Remove all creation of MixedArray and use HomArray instead

* Rename MixedArray to Tuple

* Fix to coerce arrays the way tuples are done

* Restructure to appease the type signature extraction

* Fix TS unit test

* Update output after switch to HomArray

* Update docs

* Fix to remove edge case when creating points

* Update docs with broken point signature

* Fix display of tuples to not collide with arrays

* Change push to an array with type mismatch to be an error

* Add sim test for push type error

* Fix acription to more general array element type

* Fix to coerce point types

* Change array push to not error when item type differs

* Fix coercion tests

* Change to only flatten as a last resort and remove flattening tuples

* Contort code to appease doc generation

* Update docs

* Fix coerce axes

* Fix flattening test to test arrays instead of tuples

* Remove special subtype case for singleton coercion
