Implement `array` basic heap type (#5148)

`array` is the supertype of all defined array types and for now is a subtype of
`data`. (Once `data` becomes `struct` this will no longer be true.) Update the
binary and text parsing of `array.len` to ignore the obsolete type annotation
and update the binary emitting to emit a zero in place of the old type
annotation and the text printing to print an arbitrary heap type for the
annotation. A follow-on PR will add support for the newer unannotated version of
`array.len`.
