imx-parser: bump to version 4.2.1, enable on AArch64

Changelog:
1. Upgrade EULA to v18
2. Bugfixes/Optimization
 - Update HEVC PARSER 01.00.02/ APE PARSER 00.00.08/ MPEG2 PARSER 04.05.10
   1. Delete the useless label in HEVC PARSER.
   2. Fix 2 variables' not init in special case for APE PARSER.
   3. Fix one struct's not init for MPEG2 PARSER.
 - Fix one mp3 can't play on jb4.3_1.1.1-ga
   ID3V2 contains a picture larger than 3MB, need to save ID3 data size
   in self->m_dwID3V2Size to let parser skip it when starting playback.
 - Fix creating parser error
   When variable value is negative, if(bytesToRead) will return true,
   modify this condition to if(bytesToRead > 0).

Note that this package now includes AARCH64 libraries for the upcoming
i.MX8 CPU family.
