imx-codec: Upgrade to v4.2.1

1. Upgrade EULA to v18

2. Bugfix/Optimization
   - AACPlus:M4A format audio only can output about 1s audio, then keep silence
     It is caused by AACPlus decoder because aacplus decoder
     occupys much cpu time when decoding.
     Add -O3 build option into aacplus decoder's build script to
     optimize the code.

   - Optimize the code
     Cancel duplicated code in aac_dec/aacplus_dec.
     Cancel unused code in flac_dec.
