Disambiguate let port names and types

Browse Source 
A let port can start with its name (`let l(T) = T;`) or a named type
(`let l(T value) = value;`). Parse the optional type, name and dimensions
together using the existing declaration rule.

This is in preparation for removing TYPE_IDENTIFIER. Keep the explicit
`untyped` alternative separate and remove the unused let_formal_type rule.
Let declarations remain unsupported.
