GLArrayData: Promote sealed() from GLArrayDataEditable, to correctly being used for getElemCount() instead of 0==position, ... (API change)

API Change
- sealed() moved up from GLArrayDataEditable -> GLArrayData
- GLArrayDataWrapper is sealed by default
- getSizeInBytes() -> getByteCount()
- Semantics of getElemCount() and getByteCount()
  - Correctly use sealed() to switch from position to limit - instead of 0==position

Aligned method names:
- getElemCount()
- elemPosition()
- remainingElems()
- getElemCapacity()

to corresponding byte counts:
- getByteCount()
- bytePosition()
- remainingBytes()
- getByteCapacity()
