Migrate ADIS16550 to common RX parent

[tfcollins]

Summary

• migrate ADIS16550 from direct rx/context_manager inheritance to rx_def
• preserve the public device/trigger constructor and configure dynamic names before common-parent discovery
• move channel wrappers, trigger routing, and the 16-sample default buffer into __post_init__
• add emulator-backed regressions for all 13 channels, wrapper types, trigger disablement, device identity, and buffered reads

Verification

• pytest -q --emu test/test_adis16550.py test/test_adis16507.py test/test_refactored_devices_unit.py (73 passed, 28 skipped)
• pytest -q (85 passed, 2060 skipped)
• pre-commit on changed files
