[DhairyaLGandhi]

Checklist

• Appropriate tests were added
• Any code changes were done in a way that does not break public API
• All documentation related to code changes were updated
• The new code follows the
  contributor guidelines, in particular the SciML Style Guide and
  COLPRAC.
• Any new documentation only uses public API

Additional context

Moves the literal_getproperty from SciMLBase to here to make it easier to remove in the future in favour of structural tangents. These are necessary to make it possible to accumulate gradients against parameters.
