This is an ongoing series of commits that are reformatting our Python
code. Reformatting is done with `black` (23.1.0).
If you end up having problems merging this commit because you have made
changes to a python file, the best way to handle that is to run `git
checkout --ours <yourfile>` and then reformat it with black.

Allow `in_call_stack` to be imported in either of the following ways:
```
command script import path/to/in_call_stack.py
command script import lldb.utils.in_call_stack
```

The in_call_stack Python script makes it possible to modify the last
breakpoint to only stop if a given function is present in the call
stack. It will check both the symbol name and the function name (coming
from the debug info, in case the binary is stripped).
To use this, you have to:
1. Import the script into lldb.
(lldb) command script import in_call_stack.py
2. Set a breakpoint and use the in_call_stack alias.
(lldb) b foo
(lldb) in_call_stack bar
Note that this alias operates on the last set breakpoint. You can re-run
the in_call_stack command to modify the condition.
