Fix wrong manipulation with ByteFragmentAtOffset

- the offset inside ByteFragmentAtOffset is the offset of the ByteBuffer from the beginning of the file, it is needed mostly for NinjaScope manipulations
- the offset inside ByteBufferFragment is the offset in the ByteBuffer, it points already at the place where lexing and parsing should begin
- add test for a big Ninja file and small ByteBuffer sizes used to read that file (the test is failing with the previous implementation)

Closes #10769.
