[NFC][Py Reformat] Reformat python files in lldb

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.

*** This commit represents a complete reformatting of the LLDB source code
*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:

Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):

find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;

The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

Fix process_events.py to auto continue the process if we attached so the process doesn't just sit there suspended.

llvm-svn: 244801

A bit more cleanup on the process_events.py to use best practices for event handling.

llvm-svn: 185089

Fixed the process_events.py example to be able to specify the platform and also use the debugger's listener.

Initial checkin of a new project: LLDB Performance Testing Infrastructure

This is a very basic implementation of a library that easily allows to drive LLDB.framework to write test cases for performance

This is separate from the LLDB testsuite in test/ in that:
a) this uses C++ instead of Python to avoid measures being affected by SWIG
b) this is in very early development and needs lots of tweaking before it can be considered functionally complete
c) this is not meant to test correctness but to help catch performance regressions

There is a sample application built against the library (in darwin/sketch) that uses the famous sample app Sketch as an inferior to measure certain basic parameters of LLDB's behavior.
The resulting output is a PLIST much like the following:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

Areas for improvement:
- code cleanups (I will be out of the office for a couple days this coming week, but please keep ideas coming!)
- more metrics and test cases
- better error checking

This toolkit also comprises a simple event-loop-driven controller for LLDB, similar yet much simpler to what the Driver does to implement the lldb command-line tool.
