[Tracking] use multi-value wasm for the plugin runner

[kwonoj]

Describe the feature

Currently, we use a wrapper struct contains ptr to the actual data to pass over data between plugin host to the plugin.

This is due to compiled wasm binary didn't support returning multi-value; i.e we could do simplifed way instead

fn some_fn() -> (ptr, len);

and receiver directly deserialize it if it was possible. We once enabled this with custom-patch, but that was too cumbersome to ask to all of the plugin authors.

It looks like recent compiler started to support it, so we may able to try this again.

However this is somewhat large breaking changes to the plugins

1. interface change requires to bump up swc_core
2. All of the plugin requires to compile with specific flag (--multi-value).

Babel plugin or link to the feature description

For now not going to pursue this as it requires all of the plugin author to compile with specific flags.
