keys: don't remove deprecated symbols by default

Browse source 
Add a new macro to mark deprecated keys. The macro will emit a warning
about the symbol being deprecated.
PW_ENABLE_DEPRECATED will suppress the deprecation warning.
Add PW_REMOVE_DEPRECATED to completely remove the deprecated symbols.

Fixes #2952
