record caller frame instead of function frame (#96882)
Previously, when starting to trace a function, we would record a frame summary recording the definition loc. This would lead to an unconventional-looking stack trace when used for debugging, e.g., shape guards.

```
As noted in https://github.com/pytorch/pytorch/pull/95848#discussion_r1134397096, we would like to change this to record function calls instead, like conventional stack traces do. This diff makes this change. The above stack now looks like the following, which is way more helpful at a glance to understand what's going on.
