Resolve Sah schema

Data::Sah::Resolve provides resolve_schema. Sah schemas can be defined in terms of other schemas as base. The resolving process follows the (outermost) base schema until it finds a builtin type as the (innermost) base. It then returns a hash result (a DefHash with v=2) containing the type as well other information like the collected clause sets and others. This routine performs the following steps: 1. Normalize the schema Unless schema_is_normalized option is true, in which case schema is assumed to be normalized already. 2. Check if the schema's type is a builtin type Currently this is done by checking if the module of the name Data::Sah::Type::<type> is loadable. If it is a builtin type then we are done. 3. Check if the schema's type is the name of another schema This is done by checking if Sah::Schema::<name> module exists and is loadable. If this is the case then we retrieve the base schema from the $schema variable in the Sah::Schema::<name> package and repeat the process while accumulating and/or merging the clause sets. 4. If schema's type is neither, we die.
