drivers/sensors: Legacy sensor warning

This commit implements a compile-time warning and in-code comment
warning for legacy sensor drivers. This is intended to:

- Warn users that legacy drivers may eventually be removed
- Warn developers that they should not use a legacy driver as a
  reference for their new driver contributions
