Mark the session as receiving around nghttp2_session_mem_recv() and defer RST_STREAM handling while receive is in progress. This prevents closing a stream while nghttp2 still processes it and avoids heap-use-after-free in nghttp2_session_mem_recv2().

Backport of #64166 to
v26.x-staging.Original PR: http2: avoid uaf while receiving and sending rst_stream
Fixes: #64113
Backport note
The upstream fix relies on the http2 JS close/destroy refactor from PR #63249 (
http2: error for incomplete reads on RST, auto-drain, deprecate aborted), which is semver-major and cannot be backported to a release branch. Onv26.x(which lacks that refactor) the C++ backport alone stallstest-http2-many-writes-and-destroy.js(graceful close never completes — the server's GOAWAY is not flushed because theSendPendingData()guard returns busy duringnghttp2_session_mem_recv()).So this backport includes a second commit that drops the send guard. The primary UAF protection (the RST_STREAM / Destroy / Close deferrals) remains intact, and the full http2 suite passes.
