Pretty Printer: Fix printing of conversion operator decls and calls.

- Don't emit anything when we encounter a call to a conversion operator.
    "bar(a & b)" instead of "bar(a & b.operator int())"
  This preserves the semantics and is still idempotent if we print the AST multiple times.

- Properly print declarations of conversion operators.
    "explicit operator bool();" instead of "bool operator _Bool();"

PR18776.
