feat(turbopack): externalType support script

[fireairforce]

This pr introduce a new external type: Script, which has the same behaviour as webpack's https://webpack.js.org/configuration/externals/#externalstypescript

And i also refer to the webpack's implement, this external type accept a request like: root@script_url which same as webpack:

In the utoo, we use it as follows:

https://github.com/umijs/mako/blob/next/crates/pack-core/src/shared/resolve/externals_plugin.rs#L202-L208

It will generate runtime code to load the external package from the script_url
