This fixes the cosmopolitan platform.
- Switch `build_cosmocc.sh` and platform documentation to
explicitly use the x86_64 cosmocc compiler as multi-arch
cosmocc won't work here. Older version `cosmocc` just did
a x86_64 build.
- Add missing items from `platform_internal.h` to fix build.
This PR adds the Cosmopolitan Libc platform enabling compatibility with multiple
x86_64 operating systems with the same binary. The platform is similar to the
Linux platform, but for now only x86_64 with interpreter modes are supported.
The only major change to the core is `posix.c/convert_errno()` was rewritten to use
a switch statement. With Cosmopolitan errno values depend on the currently
running operating system, and so they are non-constant and cannot be used in array
designators. However, the `cosmocc` compiler allows non-constant case labels in
switch statements, enabling the new version.
And updated wamr-test-suites script to add `-j <platform>` option. The spec tests
can be ran via `CC=cosmocc ./test_wamr.sh -j cosmopolitan -t classic-interp`
or `CC=cosmocc ./test_wamr.sh -j cosmopolitan -t fast-interp`.
- Provide a Dockerfile.old to fix issue of ESP32 custom linker scripts not working
properly with the newer version of Zephyr, as reported in #2263
- Provide a Dockerfile with newer Zephyr for other boards
- Update the corresponding document
Removes the `west espressif install` command which is no longer
supported.

Also adds a reference to the Zephyr SDK, which will install the
necessary toolchains for all supported targets.
