This patch tries to fix an issue with the windows debug builds where the
PDB file for python scripted interfaces cannot be opened since its path
length exceed the windows `MAX_PATH` limit:

https://github.com/llvm/llvm-project/pull/101672#issuecomment-2289481324

This patch addresses the issue by building all the interfaces as a
single library plugin that initiliazes each component as part of its
`Initialize` method, instead of building each interface as its own
library plugin.

This keeps the build artifact path length smaller while respecting the
naming convention and without making any exception in the build system.

Fixes #104895.

This patch introduces a new `template` multiword sub-command to the
`scripting` top-level command. As the name suggests, this sub-command
operates on scripting templates, and currently has the ability to
automatically discover the various scripting extensions that lldb
supports.

This was previously reviewed in #97273.

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.
