patch 9.0.2076: Vim9: No support for type aliases
Problem: Vim9: No support for type aliases
Solution: Implement :type command
A type definition is giving a name to a type specification. This also known
type alias.
:type ListOfStrings = list<string>
The type alias can be used wherever a built-in type can be used. The type
alias name must start with an upper case character.
