[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.

Python 2/3 compat: unichr vs chr

Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

*** 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.

Several performance-oriented changes to the introspecting data formatters:
(a) the SystemParameters object is now passed around to the formatters; doing so enables the formatters to reuse computed values for things such as pointer-size and endianness
instead of repeatedly computing these on their own
(b) replacing the global ISA cache with a per-process one
(c) providing a per-process types cache where each formatter can store the types it needs to operate, and be sure to find them the next time without recalculating them
this also enables formatters to share types if they agree on a local naming convention
(d) lazy fetching of data from Objective-C runtime data structures
data is fetched as needed and we stop reading as soon as we determine that an ISA is actually garbage

This commit:
a) adds a Python summary provider for NSDate
b) changes the initialization for ScriptInterpreter so that we are not passing a bulk of Python-specific function pointers around
c) provides a new ScriptInterpreterObject class that allows for ref-count safe wrapping of scripting objects on the C++ side
d) contains much needed performance improvements:
1) the pointer to the Python function generating a scripted summary is now cached instead of looked up every time
2) redundant memory reads in the Python ObjC runtime wrapper are eliminated
3) summaries now use the m_summary_str in ValueObject to store their data instead of passing around ( == copying) an std::string object
e) contains other minor fixes, such as adding descriptive error messages for some cases of summary generation failure

This patch provides a set of formatters for most of the commonly used Cocoa classes.
The formatter for NSString is an improved version of the one previously shipped as an example, the others are new in design and implementation.
A more robust and OO-compliant Objective-C runtime wrapper is provided for runtime versions 1 and 2 on 32 and 64 bit.
The formatters are contained in a category named "AppKit", which is not enabled at startup.
