4d34b286 - Set 4MB stack size for all threads, introduce `UV_STACK_SIZE` (#12839)

Set 4MB stack size for all threads, introduce `UV_STACK_SIZE` (#12839) See #12769 for the motivation. We set the 4MB not only for the main thread, but also for all tokio and rayon threads to fix a stack overflow while unpacking wheels in production on Windows. There are two variables for setting the stack size: A new `UV_STACK_SIZE` that takes precedent, and the existing `RUST_MIN_STACK`. When setting the stack size, `UV_STACK_SIZE` should be preferred, since `RUST_MIN_STACK` affects all Rust applications, including build backends we call (e.g., maturin). The minimum stack size is set to 1MB, the lowest stack size we observed on a platform (Windows main thread). Fixes #12769 ## Test Plan Tested manually with the example from #12769
