Refactoring the shacl_validation crate according to the refactoring of the core of rudof

[angelip2303]

• Use a template method in the constraint components traits
• Improve the naming / use of iterators in the FocusNodes and ValueNodes structs
• Improve the naming of the parameters to the shape validate method
• Remove the Debug + 'static constraints in the generics
• Improve how the constraint components are compiled
• Improve the implementation of the conversion to IriS for Constraint Components
• Improve the Validate Error
• Remove the store module, no longer needed
• Merge the NativeValidator and Validator traits
• Currently we have an expect in the FocusNodes implementation for CompiledShape
• Try replacing the fully-qualified syntax by something more concise
• Improve the checks for equality of the ValidationReport according to the SHACL recommendation
• Remove unnecessary SRDF helper
• Remove unnecessary clones
• Remove some unnecessary references in the parameters
• Constraint may raise an Error when evaluated, change the functions accordingly
• Replace the Deref thing in the constraints by something else, we are trying to emulate inheritance, and that is not idiomatic to Rust
• There's no need for having two validator traits
