Updated openjpeg to 2.5.2

[radarhere]

openjpeg 2.5.2 has been released - https://github.com/uclouvain/openjpeg/releases/tag/v2.5.2

This reverts the patch from #6718

[moubctez]

OpenJPEG 2.5.1 defines OPJ_VERSION_MAJOR, so this

/* OpenJPEG 2.0 doesn't have OPJ_VERSION_MAJOR */
#ifndef OPJ_VERSION_MAJOR

is no longer valid (in src/libImaging/Jpeg2KEncode.c and src/libImaging/Jpeg2KDecode.c).

[radarhere]

From what I can see, OPJ_VERSION_MAJOR has been around since OpenJPEG 2.1.0 - so I think the comment meant 2.0.x, not 2.x.

So for this segment,

Pillow/src/libImaging/Jpeg2KDecode.c

Lines 671 to 675 in 0fc9b91

	/* OpenJPEG 2.0 doesn't have OPJ_VERSION_MAJOR */
	#ifndef OPJ_VERSION_MAJOR
	opj_stream_set_user_data(stream, state);
	#else
	opj_stream_set_user_data(stream, state, NULL);

the intention is to call the earlier version of opj_stream_set_user_data for earlier OpenJPEG versions.
