feat: add type representation in vm package

Type and Value types in vm package are now used in place of reflect.Type
and reflect.Value. It allows to remove the dependency on reflect for
parser and compiler packages.

The main purpose of Type is to provide a solution to implement recursive
structs, named types, interfaces and methods, despite the limitations of
Go reflect. The goal is to provide the thinnest layer around reflect.
