flatten: simplify.
...
`flatten` cannot derive modules in most cases because that would just
yield processes, and it does not support `-autoproc`; in practice
`flatten` has to be preceded by a call to `hierarchy`, which makes
deriving unnecessary.

techmap, flatten: remove dead options.
...
After splitting the passes, some options can never be activated,
and most conditions involving them become dead. Remove them, and also
all of the newly dead code.

flatten: split from techmap.
...
Although the two passes started out very similar, they diverged over
time and now have little in common. Moreover, `techmap` is extremely
complex while `flatten` does not have to be, and this complexity
interferes with improving `flatten`.

Add WASI platform support.
...
This includes the following significant changes:
* Patching ezsat and minisat to disable resource limiting code
on WASM/WASI, since the POSIX functions they use are unavailable.
* Adding a new definition, YOSYS_DISABLE_SPAWN, present if platform
does not support spawning subprocesses (i.e. Emscripten or WASI).
This definition hides the definition of `run_command()`.
* Adding a new Makefile flag, DISABLE_SPAWN, present in the same
condition. This flag disables all passes that require spawning
subprocesses for their function.

deminout: prevent any constant assignment from demoting to input
...
Before this patch,
```
module top(inout io);
assign io = 1'bx;
endmodule
```
would have the `io` pin demoted to input (same happens for `1'bz`,
but not for `1'b0` or `1'b1`), resulting in check failures later on.
Part of fix for #1841 .
