Rework ExprMacro base classes to simplify implementations. (#15622)
* Rework ExprMacro base classes to simplify implementations.

This patch removes BaseScalarUnivariateMacroFunctionExpr, adds
BaseMacroFunctionExpr at the top of the hierarchy (a suitable base class
for ExprMacros that take either arrays or scalars), and adds an
implementation for "visit" to BaseMacroFunctionExpr.

The effect on implementations is generally cleaner code:

- Exprs no longer need to implement "visit".
- Exprs no longer need to implement "stringify", even if they don't
  use all of their args at runtime, because BaseMacroFunctionExpr has
  access to even unused args.
- Exprs that accept arrays can extend BaseMacroFunctionExpr and
  inherit a bunch of useful methods. The only one they need to
  implement themselves that scalar exprs don't is "supplyAnalyzeInputs".

* Make StringDecodeBase64UTFExpression a static class.

* Remove unused import.

* Formatting, annotation changes.
