fix(core): use Promise.allSettled in TracingSDK flush/shutdown

Switch TracingSDK.flush() and shutdown() from Promise.all to
Promise.allSettled to prevent one provider's rejection from
abandoning the other providers' in-flight exports.

This fixes an issue where user-emitted trace data (logger.info
calls, child spans) could be silently dropped on shutdown when
any provider fails to flush, particularly affecting self-hosted
deployments with processKeepAliveEnabled: false.

Fixes #3556
