[hal] Clean up references to removed HAL features (#8695)

#7695, #7696, #7697, #7701, #7724, #7753, #7861 removed various features
from the HAL, but forgot to clean up the handles, the WS API, or both.
Additionally, since AnalogInput is the only remaining analog I/O,
AnalogJNI was renamed to the more specific AnalogInputJNI.
