[Capture location] Altitude and accuracy probably not stored in Firebase

[gino-m]

This code is not reachable:

ground-android/ground/src/main/java/com/google/android/ground/persistence/remote/firebase/schema/SubmissionMutationConverter.kt

Lines 89 to 91 in 462d28b

	is CaptureLocationTaskData -> {
	CaptureLocationResultConverter.toFirestoreMap(taskData).getOrThrow()
	}

...since CaptureLocationTaskData extends GeometryTaskData, which is handled in the previous is statement.

CaptureLocationTaskData doesn't need to extend GeometryTaskData, it can be an independent type with similar fields.

@shobhitagarwal1612 Can you take a look?
