…ites (#78934)

**The default timeout is 1 minute.** This PR reduces the timeouts for these tests from 4 minutes to 1 minute.

Maybe these overrides made sense at some point, but turbopack shouldn't ever be significantly slower than webpack in any test (if it is, that's a bug), so we shouldn't need larger timeouts for these.

This long 4 minute timeout has contributed to github action job timeouts we've previously experienced for the arewerspack/areweturboyet nightly jobs, so IMO it's hurting more than it's helping.

Add a `hoisted: bool` to `ChunkingType::Parallel` in preparation for scope hoisting (we can only merge modules if they are importing each other with ESM-import-style references (i.e. `hoisted: true`).

…tive code (#78944)

The following jobs do not depend on `build-native`, but don't specify `skipNativeBuild`:

- `lint`
- `test-devlow`
- `test-next-swc-wasm`
- `test-next-swc-napi-wasi` *(currently disabled)*
- `test-unit` *(does actually appear to depend on native binaries)*

That means that they still build the native binary, but they don't wait for `build-native` to finish first, so they don't use the cached version (they run before the cache is populated), and instead each spend 5 minutes of CPU time rebuilding the native binary.
