MLK-19247: mxc-jpeg: Remove jpeg-encoder hardcoding to 64x64 yuv422

Remove hardcodings for encoder (configuration stream especially).
This fix also requires a fixed version of the test applications,
encoder_test.out/decoder_test.out (linux-test repo).

Also fixed MLK-19453: Add support for YUV420 format in jpeg decoder
YUV420 is generally working on encoder/decoder,
but for some particular small files the decoder enters infinite error:
"Instance released before the end of transaction".
RGB24 is working, but the colors are strange in jpeg.
Since YUV444 and RGB24 have the same subsampling,
a RGB24 raw file can be encoded/decoded as YUV444 with the same results.
Fixes for invalid pixel formats.
Full battery of tests run.
