Auto merge of #138893 - klensy:thorin-0.9, r=Mark-Simulacrum

bump thorin to 0.9 to drop duped deps

Bumps `thorin`, removing duped deps.

This also changes features for hashbrown:
```
hashbrown v0.15.2
`-- indexmap v2.7.0
    |-- object v0.36.7
    |-- wasmparser v0.219.1
    |-- wasmparser v0.223.0
    `-- wit-component v0.223.0
    |-- indexmap feature "default"
    |-- indexmap feature "serde"
    `-- indexmap feature "std"
|-- hashbrown feature "default-hasher"
|   |-- object v0.36.7 (*)
|   `-- wasmparser v0.223.0 (*)
|-- hashbrown feature "nightly"
|   |-- rustc_data_structures v0.0.0
|   `-- rustc_query_system v0.0.0
`-- hashbrown feature "serde"
    `-- wasmparser feature "serde"
```
to
```
