Expression language capability

[pvlasov]

Currently SpEL is the hardcoded expression language for reflective wiring annotations (https://docs.nasdanika.org/core/graph/index.html#wiring).

With the introduction of the capability framework it makes sense to add support of multiple expression languages:

• Add expressionLanguage attribute to annotations which evaluate expressions. Set default to spel
• Create ExpressionLanguageRequirement record taking language name
• Add SpEL capability factory in the capability module
• Add Groovy capability factory in the groovy module (create)
• For annotations in common (Reflector) - create a subclass in Capability (CapabilityReflector) overriding methods which evaluate expressions, keep SpEL as default in common, throw UnsupportedOperationException for languages other than SpEL
• Update Javadoc in annotations which use SpEL
• Also update AbstractDrawioFactory and documentation
