[BOLT] Fix typos (#68121)
Closes https://github.com/llvm/llvm-project/issues/63097

Before merging please make sure the change to
bolt/include/bolt/Passes/StokeInfo.h is correct.

bolt/include/bolt/Passes/StokeInfo.h

```diff
  //  This Pass solves the two major problems to use the Stoke program without
- //  proting its code:
+ //  probing its code:
```

I'm still not happy about the awkward wording in this comment.

bolt/include/bolt/Passes/FixRelaxationPass.h

```
$ ed -s bolt/include/bolt/Passes/FixRelaxationPass.h <<<'9,12p'
// This file declares the FixRelaxations class, which locates instructions with
// wrong targets and fixes them. Such problems usually occures when linker
// relaxes (changes) instructions, but doesn't fix relocations types properly
// for them.

[NFC][Py Reformat] Reformat python files in the rest of the dirs
This is an ongoing series of commits that are reformatting our
Python code. This catches the last of the python files to
reformat. Since they where so few I bunched them together.

Reformatting is done with `black`.

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.

If you run into any problems, post to discourse about it and
we will try to help.

96f6ec5090 [BOLT] Mark option values of --split-functions deprecated
The SplitFunctions pass does not distinguish between various splitting
modes anymore. This change updates the command line interface to

4ae83bb2b1 Update all LLVM documentation mentioning runtimes in LLVM_ENABLE_PROJECTS
We are moving away from building the runtimes with LLVM_ENABLE_PROJECTS,
however the documentation was largely outdated. This commit updates all
the documentation I could find to use LLVM_ENABLE_RUNTIMES instead of
LLVM_ENABLE_PROJECTS for building runtimes.

Note that in the near future, libcxx, libcxxabi and libunwind will stop
supporting being built with LLVM_ENABLE_PROJECTS altogether. I don't know
what the plans are for other runtimes like libc, openmp and compiler-rt,
so I didn't make any changes to the documentation that would imply
something for those projects.

Once this lands, I will also cherry-pick this on the release/14.x branch
to make sure that LLVM's documentation is up-to-date and reflects what
we intend to support in the future.

1c5d3a056c Rebase: Merge BOLT codebase in monorepo
Summary:
This commit is the first step in rebasing all of BOLT
history in the LLVM monorepo. It also solves trivial build issues
by updating BOLT codebase to use current LLVM. There is still work
left in rebasing some BOLT features and in making sure everything
is working as intended.

History has been rewritten to put BOLT in the /bolt folder, as
opposed to /tools/llvm-bolt.
