Support Priority Work on Connections

[nibanks]

Description

Sometimes an application would like to prefer new work over existing work already queued on the connection. This PR adds the notion of priority to the connection's operation queue, and exposes flags through the API to allow the app to chose to leverage this.

Testing

SpinQuic updated. Need to add some explicit BVTs.

Means you're not calling new correctly. You need to use the std::nothrow version.

CIFulzz is failling in QuicConnRelease, by CXPLAT_TEL_ASSERT(Connection->RefTypeCount[QUIC_CONN_REF_STREAM] > 0). I believe that QuicOperationFree is not called as expected? and Stream might not be released.

Any idea of affecting releasing Operation by changing operation order.
