feat(compiler): add FunctionStatementProcessor and refactor related c…
…lasses #24 - Introduced a new class FunctionStatementProcessor to handle function statements. - Refactored QueryStatementProcessor to extend FunctionStatementProcessor, removing duplicate code. - Updated HobbitHole and ShireLifecycleTest to accommodate changes in function execution. - Modified TaskRoutes to use the new FunctionStatementProcessor. - Adjusted PatternActionProcessor to use the refactored QueryStatementProcessor.
