Fix deprecation warnings

[SamuelGadiel]

This PR resolves #1035

Migrated from deprecated LocationRequest to Priority
Priority doesn't have a PRIORITY_NO_POWER property, according to its documentation we should use PRIORITY_PASSIVE

LocationRequest.PRIORITY_NO_POWER -> Priority.PRIORITY_PASSIVE

---

On SDK 31+ location.isFromMockProvider() is deprecated, but older versions of android still uses it, so we have to annotate the method with @SuppressWarnings("deprecation")
If the project is running sdk 31+ we use location.isMock(), otherwise we fallback to location.isFromMockProvider()

---

For the LocationRequest.create() we have to use the new builder LocationRequest.Builder(). The parameters are passed to the builder, and not the mLocationRequest directly

---

The new Long() and new Float() were migrated to Number, and manipulated so we could have a proper Long and Float values

If I missed something, please point it out so I can fix it
