msm8960: audio: Fix for QCOM's HW AAC encoder

- CTS test(testAACEncoders) fails due to limitation of
 QCOM's HW AAC encoder. So, removed it from
 media_codecs_8960.xml to use Google's AAC encoder
 by default
- Also added entry in system.prop to enable QCOM HW
 AAC encoder: qcom.hw.aac.encoder=true
- QCOM's HW AAC encoder is enabled in frameworks code
 when qcom.hw.aac.encoder=true

msm8960: Set the default composition type as GPU.

Most targets that use the msm8960 target use GPU composition. If
the composition type needs to be set to some other value, override
the setting via the early_boot script.
