- updates the SDE action to v2.2
- removes the linux x86-32 builds, which were almost unused,
and the build process under SDE started failing recently,
possibly related to glibc update (The futex facility returned an unexpected error code.)

The UCI protocol is rather technical and has little value in our README. Instead
it should be explained in our wiki. "Contributing" is moved above "Compiling
Stockfish" to make it more prominent.
Also move the CONTRIBUTING.md into the root directory and include it in the
distributed artifacts/releases.

allows for building x86-64-avx2 and x86-64-bmi2 binaries for mac
install coreutils
show hardware capabilities as seen by the compilers
move some tests from sse41 to avx2 as platforms support it

Explicitly describe the architecture as deprecated,
it remains available as its current alias x86-64-sse41-popcnt
CPUs that support just this instruction set are now years old,
any few years old Intel or AMD CPU supports x86-64-avx2. However,
naming things 'modern' doesn't age well, so instead use explicit names.
Adjust CI accordingly. Wiki, fishtest, downloader done as well.

use a fixed compiler on Linux and Windows (right now gcc 11).
build avxvnni on Windows (Linux needs updated core utils)
build x86-32 on Linux (Windows needs other mingw)
fix a Makefile issue where a failed PGOBENCH would not stop the build
reuse the WINE_PATH for SDE as we do for QEMU
use WINE_PATH variable also for the signature
verify the bench for each of the binaries
do not build x86-64-avx2 on macos

use intel's Software Development Emulator (SDE) in the actions that build the binaries.
This allows for building on Windows and Linux binaries for
- x86-64-avx512
- x86-64-vnni256
- x86-64-vnni512
(x86-64-avxvnni needs more recent gcc in the actions)
also build x86-64-avx2 on macos.

using github actions, create a prerelease for the latest commit to master.
As such a development version will be available on github, in addition to the latest release.

For development versions of Stockfish, the version will now look like
dev-20221107-dca9a0533
indicating a development version, the date of the last commit,
and the git SHA of that commit. If git is not available,
the fallback is the date of compilation. Releases will continue to be
versioned as before.
Additionally, this PR extends the CI to create binary artifacts,
i.e. pushes to master will automatically build Stockfish and upload
the binaries to github.
