perf(turbo-tasks): Optionally schedule ResolveNative/ResolveTrait tasks as local tasks

[bgw]

When calling a turbo tasks function with unresolved arguments, we create a wrapper CachedTaskType::ResolveNative or ResolveTrait task.

These are quite frequently created, and their behavior is constrained and well-defined, so we should turn them into local tasks that aren't cached in the backend.

This logic is gated behind --features turbo-tasks/local_resolution, as it has some known issues.

Known Issues

A RawVc::LocalOutput can currently only be resolved within it's parent task.

The long-term plan is for everything to use ResolvedVc, so that this assumption is safe.

The short-term plan is to store local outputs more globally. Design here: https://www.notion.so/vercel/RawVc-LocalOutput-aede5f463f594ca58396eb3fdaffd865?pvs=4#02af94e3b9b64a3690f3e467abc0a47e

Test Plan

cargo nextest r --features turbo-tasks/local_resolution -p turbo-tasks -p turbo-tasks-memory

Closes PACK-3762
