AArch64: Fix GetChannelCount() declaration.

Two fixes
[x] GetChannelCount() return type is size_t in the declaration and
    SLuint32 in the definition. It should be SLuint32 in both places.
[x] CreateAndRealizeAudioPlayer has a size_t parameter channelCount.
    This should should be SLuint32 as the actual parameter is SLuint32.
