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.

The DynamicLoaderPOSIXDYLD::GetStepThroughTrampolinePlan() function was
doing the symbol lookup using the demangled name. This stopped working
with https://reviews.llvm.org/D118814. To get things working again, just
use the mangled name for the lookup instead.
