This PR builds our own `Debug`-like derive-macro machinery for formatting structs, relying on `std::fmt::Formatter` for the actual formatting.
### Usage
A new `ValueDebug` trait is automatically implemented for all `#[turbo_tasks::value]`s, which has a single `.dbg()` method which resolves to a debug representation that can then be printed to the screen. `#[turbo_tasks::value_trait]` also implement the `.dbg()` method directly.
```rust
dbg!(any_vc.dbg().await?);
```
If you have a `#[turbo_tasks::value]` struct with a field that doesn't implement `Debug`, you'll want to declare that field as `#[debug_ignore]`. For instance:
```rust
#[turbo_tasks::value(ContentSource, serialization: none, eq: manual, cell: new, into: new)]
pub struct TurboTasksSource {
#[debug_ignore]
#[trace_ignore]
pub turbo_tasks: Arc<TurboTasks<MemoryBackend>>,
}
```
### Why not use `Debug` directly?
We can't use `Debug` because our values are resolved asynchronously and can nest `Vc`s arbitrarily. I tried using `futures::executor::block_on` to resolve them synchronously in a `Debug` implementation but that causes deadlocks.
Cherry-picking this from my work on the next-dev test runner.
This moves browser opening from the turbopack-dev-server crate into the next-dev crate, which has the cli entrypoint that runs the dev server. It looks like the dev server package is meant to be used as a library (it's only a library crate), and having this external side effect feels unexpected and makes it difficult to use this crate in situations like a test runner for next-dev, where we should test with a headless web browser.
Alternatively, opening the browser could be an option passed when creating the dev server, but this feels a bit cleaner to me.
Test Plan: `cargo run -p next-dev` and verify the browser still opens and successfully connects to the dev server.
