Support new clang mangling of main (__main_argc_argv) (#2671)
The plan is that for standlone mode we can function just like wasi-sdk
and call the correct main from crt1.c.
For non-standalone mode we still want to export can call main directly
so we rename __main_argc_argv back to main as part of finalize.
See https://reviews.llvm.org/D70700
