Remove tsl::internal::PickUnusedPort, tsl::internal::PickUnusedPortOrDie, and tsl::internal::RecycleUnusedPort, which are marked with ABSL_DEPRECATE_AND_INLINE() in favor of the tsl::net equivalents. Update the forwarding declaration in tensorflow/core/platform/net.h to alias tsl::net::PickUnusedPortOrDie.

Tag host program enqueue and completion TraceMe events with the kTraceHostEnqueueCallback filter bit.
#3678copybara-service[bot] opened Nov 5, 2026Bot
Add TraceMeFilter::kTraceHostEnqueueCallback = 1 in trace_filter_utils.h, and clear that bit (bit 1, mask 0x2) in kTraceMeDefaultFilterMask in traceme.h using a new kTraceMeHostEnqueueCallbackFilter constant with the same value. traceme.h cannot depend on trace_filter_utils.h, so traceme_recorder_test checks with a static_assert that the two stay equal.
