Include dependency edge info in transition errors

When a Starlark transition implementation function fails, it now prints an error such as:

```
ERROR: /home/user/example/BUILD.bazel:3:11: On dependency edge //pkg:wrapper (ed19e2b) -|exports|-> //pkg:real_target: Errors encountered while applying Starlark transition
```

Previously, the generated error messages would only point to the BUILD file location of the target with the outgoing edge as well as a stack trace of the transition function (the latter only for Starlark errors, not those encountered during option conversion).

Closes #19251.
