[ITK 5.1] itkJPEG2000ImageIO.cxx pulls in private openjpeg headers and uses wrong enumss

### Description
https://github.com/InsightSoftwareConsortium/ITK/blob/7900a8b6d63ec8201405eff3b46c8d2a4e563c45/Modules/IO/JPEG2000/src/itkJPEG2000ImageIO.cxx#L29-L31
header `jk2.h` and `jp2.h` are not getting installed by OpenJPEG. As such symbols like `CODEC_` are not available. Remove the private headers and include only `openjpeg.h` and replace `CODEC_` with `OPJ_CODEC_` (same for the `CLRSPC` enums values)

Furthermore `opj_stream_create_default_file_stream` does not accept a filehandle any more.

In general the OpenJPEG API seems to have changed quite a bit in the meantime (using 2.3.1)
