Improve uncalled function checks (#41599)
Fixes #41586
Fixes #41588

1. For binary expressions, if the immediate parent is an IfStatement,
then check the body of the if statement. I didn't walk upward to find an
IfStatement because in my experimentation I found that binary expression
uncalled-function errors are only issued when the expression is on the left of the
top-most binary expression.

2. For property accesses with interspersed calls, I added a
CallExpression case. In fact, any expression could appear here, but I
only want to fix calls for now since that's all we've observed in
Definitely Typed, and we didn't see anything else in the user tests or RWC
tests. I also didn't examine parameters of the intermediate call
expressions, but I don't think it's needed since the intent is to avoid
false positives.
