[wasm] Basic WASI support.
Enabling WASI when building an instance sets up the default WASI imports, and can optionally capture stdout/stderr. I'd like to set up something similar for stdin, but Wasmer doesn't support that yet. I also improved error handling in WasmRuntime by adding Wasmer's last error to the thrown exceptions where appropriate. Bug: https://github.com/dart-lang/sdk/issues/37882 Change-Id: I2d8546e878bcb43c7093490eac085aa62d318e96 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/167904 Reviewed-by: Ryan Macnak <rmacnak@google.com> Commit-Queue: Liam Appelbe <liama@google.com>
