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.
