[ctor-eval] Eval functions with params if ignoring external input (#4446)
When ignoring external input, assume params have a value of 0. This
makes it possible to eval main(argc, argv) if one is careful and does
not actually use those values.
This is basically a workaround for main always receiving argc/argv,
even if the C code has no args (in that case the compiler emits
__original_main for the user's main, and wraps it with a main
that adds the args, hence the problem).
This is similar to the existing support for handling wasi_args_get
when ignoring external input, although it just sets values of zeros for
the params. Perhaps it could check for main() specifically and return
1 for argc and a proper buffer for argv somehow, but I think if a program
wants to use --ignore-external-input it can avoid actually reading
argc/argv.
