Remove Wasm exception handling workarounds

Ensure only non-truncating values are returned from `main()`.
...
POSIX allows any `int` value to be returned but specifies that only
the low 8 bits are available in some contexts:
https://pubs.opengroup.org/onlinepubs/9699919799/functions/_exit.html
For reasons that aren't entirely clear, WASI requires the value to be
in range [0;126), and this is enforced with an assertion at runtime
level in Wasmtime. This should probably be fixed in Wasmtime but until
it is done there doesn't seem to be any harm in returning `125` instead
of `-1`. This also removes any discrepancy due to truncation.

Improve file open error messages ( #1700 )
...
Define open_(o|i)fstream_and_log_error in log.h to:
- quote 'filename'
- add error cause to easier troubleshoot
- use existing consistent string style
- easily allows OS specific message
Introduce it when file are opened and add it where error message
was missing.

CMake: refactor architecture-specific build system parts.
...
Two user-visible changes were made:
* `-DUSE_RUST` is replaced with `-DBUILD_RUST`, by analogy with
`-DBUILD_PYTHON`
* `-DCOVERAGE` was removed as it doesn't work with either modern GCC
or Clang

Various fixes for clang/libc++ build ( #1415 )
...
* Gowin: add header includes required on libstdc++.
* kernel: fix incorrect printf-style format.
* himbaechel: add missing `override` qualifiers.
* Gowin: remove unnecessary `std::move`.
These calls inhibit RVO, a stronger optimization than moving an object.

Fix handling of RNG seed

* Fix truncation of output seed value from 64 bits to 32 bits (int
instead of uint64) when written to json file.
* Fix input seed value conversion when --seed option is used.
* Remove input seed value scrambling (use of rngseed()) when --seed
or --randomize-seed option is used since the output seed value will
be the scrambled value and not the seed that was actually supplied
or generated.
