curl: fix --test-event --parallel
(in debug-builds)

Fix implementation in curl using libuv to process parallel transfers.
Add pytest capabilities to run test cases with --test-event.

- fix uv_timer handling to carry correct 'data' pointing to uv context.
- fix uv_loop handling to reap and add transfers when possible
- fix return code when a transfer errored

Closes #14413
