Summary: Cover two protocol interactions for registered-source IBGDA sends: sharing the normal send cursor with staged sends, and maintaining backpressure and data integrity across repeated staging-slot wrap. This is test-only hardening for the registered-source transport primitive. Differential Revision: D114552006

Summary: Add resumable and blocking registered-source send APIs that let IBGDA read directly from a registered caller buffer. Track posting separately from local NIC completion so callers can safely reuse the source only after an explicit drain. Preserve the existing staged protocol cursor, receiver staging, signaling, credits, and default behavior. Reviewed By: rmahidhar Differential Revision: D114552007
