Haojian Wu dc62da4e0b [clang-tidy] Check for sizeof that call functions 
Summary:
A common mistake that I have found in our codebase is calling a function to get an integer or enum that represents the type such as:

```
int numBytes = numElements * sizeof(x.GetType());
```

So this extends the `sizeof` check to check for these cases. There is also a `WarnOnSizeOfCall` option so it can be disabled.

Patch by Paul Fultz II!
