Hoist `profile.dev.package` setting to workspace-level (#10041)

Marshall Bowers created 

This PR hoists the `profile.dev.package` settings for compiling the
`resvg` crate with optimizations up to the workspace level, since Cargo
was complaining:

```
warning: profiles for the non root package will be ignored, specify profiles at the workspace root:
package:   /Users/maxdeviant/projects/zed/crates/gpui/Cargo.toml
workspace: /Users/maxdeviant/projects/zed/Cargo.toml
```

Release Notes:

- N/A
