Turbopack: move get_inner_asset into ecmascript module (#93191)
`resolve_origin.get_inner_asset` showed up in Luke's statistics at a
very high place.
But in reality, there are only 1-3 modules per page that have any inner
assets (the templates, and the edge wrapper modules).
`resolve_origin.get_inner_asset` is in the hottest hot path (resolving
references), so let's simply move this logic into the
EcmascriptModuleAsset itself.
Behavioral differences to before:
- only works with static ESM `import`s, dynamic `import()`, `require`,
`require.resolve`. But these are the only places that currently use it
anyway.
