Fix crash on first-class callable in do-while condition

- Added printer methods for MethodCallableNode, FunctionCallableNode,
  StaticMethodCallableNode, and InstantiationCallableNode to Printer
- These nodes delegate to printing their original AST node
- The crash occurred because filterByTruthyValue/filterByFalseyValue
  tried to print callable nodes that had no printer method
- New regression test in tests/PHPStan/Analyser/data/bug-12246.php

Closes phpstan/phpstan#12246
