...and "[lldb/Interpreter] Introduce `ScriptedStopHook{,Python}Interface` & make use of it (#105449)"

This reverts commit 76b827bb4d5b4cc4d3229c4c6de2529e8b156810, and commit 1e131ddfa8f1d7b18c85c6e4079458be8b419421
because the first commit caused the test command-stop-hook-output.test to fail.

This patch introduces new `ScriptedStopHook{,Python}Interface` classes
that make use of the Scripted Interface infrastructure and makes use of
it in `StopHookScripted`.

It also relax the requirement on the number of argument for initializing
scripting extension if the size of the interface parameter pack contains
1 less element than the extension maximum number of positional arguments
for this initializer.
This addresses the cases where the embedded interpreter session
dictionary is passed to the extension initializer which is not used most
of the time.

This patch removes all of the Set.* methods from Status.

This cleanup is part of a series of patches that make it harder use the
anti-pattern of keeping a long-lives Status object around and updating
it while dropping any errors it contains on the floor.

This patch is largely NFC, the more interesting next steps this enables
is to:
1. remove Status.Clear()
2. assert that Status::operator=() never overwrites an error
3. remove Status::operator=()

Note that step (2) will bring 90% of the benefits for users, and step
(3) will dramatically clean up the error handling code in various
places. In the end my goal is to convert all APIs that are of the form

`    ResultTy DoFoo(Status& error)
`
to

`    llvm::Expected<ResultTy> DoFoo()
`
How to read this patch?

The interesting changes are in Status.h and Status.cpp, all other
changes are mostly

` perl -pi -e 's/\.SetErrorString/ = Status::FromErrorString/g' $(git
grep -l SetErrorString lldb/source)
`
plus the occasional manual cleanup.

Reverts https://github.com/llvm/llvm-project/pull/97273 since it broke

This patch tries to fix the following build failure on windows:

https://lab.llvm.org/buildbot/#/builders/141/builds/1083

This started happening following 2914a4b88837, and it seems to be caused
by some special `#include` ordering for the lldb-python header on Windows.

This patch changes `ScriptedThreadPlan::GetStopDescription` behavior by
discarding its return value since it is optional in the first place (the
user doesn't need to provide a return value in their implementation).

This patch also addresses the test failures in TestStepScripted
following 9a9ec22 and re-enables the tests that were XFAIL'd previously.

The issue here was that the `Stream*` that's passed to
`ThreadPlanPython::GetDescription` wasn't being passed by reference to
the python method so it was never updated to reflect how the python
method interacted with it.

This patch solves this issue by making a temporary `StreamSP` that will
be passed to the python method by reference, after what we will copy its
content to the caller `Stream` pointer argument.

This patch makes ScriptedThreadPlan conforming to the ScriptedInterface
& ScriptedPythonInterface facilities by introducing 2
ScriptedThreadPlanInterface & ScriptedThreadPlanPythonInterface classes.

This allows us to get rid of every ScriptedThreadPlan-specific SWIG
method and re-use the same affordances as other scripting offordances,
like Scripted{Process,Thread,Platform} & OperatingSystem.

To do so, this adds new transformer methods for `ThreadPlan`, `Stream` &
`Event`, to allow the bijection between C++ objects and their python
counterparts.

This just re-lands #70392 after fixing test failures.
