Provide ABI documentation for SME similar to that for SVE. Due to the very
large overlap around streaming SVE mode in both implementation and
interfaces documentation for streaming mode SVE is added to the SVE
document rather than the SME one.

Pull documentation updates from Jonathan Corbet:
"As hoped, things calmed down for docs this cycle; fewer changes and
almost no conflicts at all. This includes:
- A reworked and expanded user-mode Linux document
- Some simplifications and improvements for submitting-patches.rst
- An emergency fix for (some) problems with Sphinx 3.x
- Some welcome automarkup improvements to automatically generate
cross-references to struct definitions and other documents
- The usual collection of translation updates, typo fixes, etc"

Add arm64 subdirectory into the table of Contents for zh_CN,
then add other translations in arm64 conveniently.

Memory Tagging Extension (part of the ARMv8.5 Extensions) provides
a mechanism to detect the sources of memory related errors which
may be vulnerable to exploitation, including bounds violations,
use-after-free, use-after-return, use-out-of-scope and use before
initialization errors.
Add Memory Tagging Extension documentation for the arm64 linux
kernel support.

This file is almost in ReST. All it needs is a rename and
adding a :field: for the two fields at the beginning
(author and date).
While here, add a proper SPDX header, and use the standard
markup for document titles, just for consistency.

The activity monitors extension is an optional extension introduced
by the ARMv8.4 CPU architecture.
Add initial documentation for the AMUv1 extension:
- arm64/amu.txt: AMUv1 documentation
- arm64/booting.txt: system registers initialisation

Documentation/arm64/tagged-address-abi.rst introduces the
relaxation of the syscall ABI that allows userspace to pass
certain tagged pointers to kernel syscalls.
Add the document to index.rst for a correct generation of the
table of content.

Now that several arch documents were converted to ReST,
add their indexes to Documentation/index.rst and remove the
:orphan: from them.
Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

The documentation is in a format that is very close to ReST format.
The conversion is actually:
- add blank lines in order to identify paragraphs;
- fixing tables markups;
- adding some lists markups;
- marking literal blocks;
- adjust some title markups.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.
