fix Issue 11677 - user defined attributes must be first

Parse prefix attributes in while loop of parseDeclDefs
fix Issue 11678 - user defined attributes cannot appear as postfixes
fix Issue 11679 - user defined attributes not allowed for local auto declarations
fix Issue 11680 - user defined attributes for type inference
fix Issue 9112 - Uniform construction for built-in types

Support syntax T(), T(v), and new T(v) for basic type T
Use defaultInitLiteral

It is more direct conversion than using typeDotExp(loc, t, Id::init).
And for scalar types, there is no difference. So this will just shorten
compilation pathway.
Added small parser fix
