Revert "disable TARGET_ENABLE_QC_AV_ENHANCEMENTS to fix video recording"

This reverts commit a42f1d336b2fc18ed6756100c64686cab07e7a53.
remove qcom.hw.aac.encoder

mako doesn't support this because they have QC enhancements disabled.
But since we need this flag to fix lags it's used on this device.
The problem is that the aac encoder doesn't seem to work.
It crashes with a message which tells you that the audio format
'audio/raw' isn't supported
