[sensors] Minor tuning of hal definition
* Swap GEOMAGNETIC_FIELD with MAGNETIC_FIELD for more accurate
definition.
* Remove redundunt prefixes in various enum definitions.
* Clarify that string type will be removed for well defined sensor
types. This avoid dependency on strings defined in sensors.h.
* Added SensorFlagShift enum.
* Remove unused flag parameter in batch.
* Remove legacy setDelay function.
* Change the type of sensor flag to bitfield<SensorFlagBits>, and
use uint32_t since only low 32 bits are used.
Test: all sensor works(in marlin), tested with sensorlogger.
