Improvement: Improve ByteBuffers performance

[WojciechMazur]

This PR continues onging effort on improving nio Buffers performance. Should allow for up to 50% faster execution (no exact benchmark data from before changes), based on debugging of 1 Billions Rows Challange in Scala Native

• All Buffers define rawAddress which is equal to address calculated from array.at(arrayOffset) / mappedData.data + offset. The only exception is StringCharBuffer which does not expose pointer to underlying arrays. It's methods are overriden.
• Use a common implemention of relativate and absolute get/put methods in TBuffer instead of using GenBuffers.
• Don't use ByteArrayBits to implement getX/putX operations on ByteBuffers. Use pointer directly. Each usage of ByteArrayBits coused creation of new instance of this class. ByteArraBits are still used in BufferViews
