This PR introduces a few changes to improve turbopack compatibility and
ensure e2e tests pass with turbopack enabled
## Changes to improve turbopack compatibility
- Use correct sideEffects configuration to fix scss issues
- Import scss directly instead of duplicating our scss rules
- Fix some scss rules that are not supported by turbopack
- Bump Next.js and all other dependencies used to build payload
## Changes to get tests to pass
For an unknown reason, flaky tests flake a lot more often in turbopack.
This PR does the following to get them to pass:
- add more `wait`s
- fix actual flakes by ensuring previous operations are properly awaited
## Blocking turbopack bugs
- [X] https://github.com/vercel/next.js/issues/76464
- Fix PR: https://github.com/vercel/next.js/pull/76545
- Once fixed: change `"sideEffectsDisabled":` back to `"sideEffects":`

### What?
Swaps out `deepAssertEqual` for `dequal` package. Further details and
motivation in [this
discussion](https://github.com/payloadcms/payload/discussions/12192).
### Why?
Dequal is about 100x faster in limited local testing. Dequal package
shows 3-5x speed over `deepAssertEqual` in benchmarks. Memory usage is
within acceptable levels.
### How?
Move the result of dequal to a `const` for readability. Replace the `try
{ ... } catch { ... }` with `if { ... } else { ... }` for minimum impact
and change.
In 3.0, we made the decision to export all types from the main package
export (e.g. `payload/types` => `payload`). This improves type
discoverability by IDEs and simplifies importing types.
This PR does the same for our db adapters, which still have a separate
`/types` subpath export. While those are kept for
backwards-compatibility, we can remove them in 4.0.
