Code fix to extract an in-line type to a type declaration

If the user writes:
```bicep
param image {
registry: string
name: string
tag: string
}
```

It would be nice to offer a code fix such as the following, where the cursor is on `|`, and typing changes both usages of `|`
```bicep
type | {
registry: string
name: string
tag: string
}

param image |
```

No files, tests, or entry points are named. Start by locating the existing Bicep code-fix infrastructure and related type-declaration handling. Done means the fix extracts the inline object type, updates the parameter to reference the new declaration, and preserves both usages of the chosen name.
