Provide the APIF MMIO transport, DART/SART ownership backends, T6050 CPU identification, shared RTKit/mailbox support, and common consumer interfaces on Linux 7.3. The native platform drivers continue to use their existing paths. Shared headers, build declarations, documentation, and host-test support let the remaining driver changes be reviewed as sibling PRs.

#472 added a T6050 PMP registry-v2 path to apple_rtkit_rx_work(): endpoint 7 now goes to apple_rtkit_pmp_aux_rx() when rtk->pmp_registry_v2 is set. The ordered-rx fixture extracts apple_rtkit_rx_work(), but its struct apple_rtkit has no such field and nothing defines the new handler, so the group stopped compiling and the apple-dcp host suite went from 80/80 to 79/80 on integration/aurora. Give the fixture struct apple_rtkit the field and stub the handler the way the CoreAnalytics one is stubbed, as unreachable in this fixture. No assertion changes. The edid group also still passes on the tree before #472, where the stub is unused.
