Now that we have tools/lib/python for our Python modules, turn them into
proper packages with a single namespace so that everything can just use
tools/lib/python in sys.path. No functional change.

"scripts/lib" was always a bit of an awkward place for Python modules. We
already have tools/lib; create a tools/lib/python, move the libraries
there, and update the users accordingly.
While at it, move the contents of tools/docs/lib. Rather than make another
directory, just put these documentation-oriented modules under "kdoc".

Move the kernel build options abbreviations to the .txt file so that
they are together instead of one having to go hunt them in the .rst
file.
Tweak the formatting so that the inclusion of kernel-parameters.txt
still keeps the whole thing somewhat presentable in the html output too.

Since the beginning, SPHINXDIRS was meant to be used by any
subdirectory inside Documentation/ that contains a file named
index.rst on it. The typical usecase for SPHINXDIRS is help
building subsystem-specific documentation, without needing to
wait for the entire building (with can take 3 minutes with
Sphinx 8.x and above, and a lot more with older versions).
Yet, the documentation for such feature was written back in
2016, where almost all index.rst files were at the first
level (Documentation/*/index.rst).
Update the documentation to reflect the way it works.

Commit 0122938a7a ("rtla: Always set all tracer options") changed the
behavior of RTLA to always set all osnoise and timerlat tracer options
to default values taken from the tracers whenever an RTLA measurement
is started. The change was done to make RTLA results consistent on
subsequent runs of the same command.
Include the default values for tracer options also in documentation
where appropriate.

Our documentation-related tools are spread out over various directories;
several are buried in the scripts/ dumping ground. That makes them harder
to discover and harder to maintain.
Recent work has started accumulating our documentation-related tools in
/tools/docs. This series nearly completes that task, moving most of the
rest of our various utilities there, hopefully fixing up all of the
relevant references in the process.
The one exception is scripts/kernel-doc; that move turned up some other
problems, so I have dropped it until those are ironed out.
At the end, rather than move the old, Perl kernel-doc, I simply removed it.
Chinese translation docs for 6.18
This is the Chinese translation subtree for 6.18. It includes
the following changes:
- docs/zh_CN: Add rust Chinese translations
- docs/zh_CN: Add scsi Chinese translations
- docs/zh_CN: Add gfs2 Chinese translations
- Add some other Chinese translations and fixes
Above patches are tested by 'make htmldocs'
