Add warning about should_drop for JIT coverage plug-in (#57961)
Summary:
This adds a comment above `should_drop` to prevent someone from inadvertently breaking JIT coverage by renaming the function without updating the correct references.
The current JIT plug-in uses `should_drop` to figure out which code is going to be JIT'd. If the function is named differently, the plug-in would also need to be updated.
Question: I understand this may not be the cleanest solution. Would a cleaner solution be to create a dummy function that would simply exist for the JIT plug-in? I did not immediately do that as that may be adding unnecessary code complexity in torch.jit.
