Refactor audio_coding/ilbc: removes usage of macro WEBRTC_SPL_LSHIFT_W32

Browse Source 
The macro is defined as
#define WEBRTC_SPL_LSHIFT_W32(a, b) ((a) << (b))
It is a trivial operation that need no macro. In fact it may be confusing for to the user, since it can be interpreted as having an implicit cast to int32_t.

Also removes unnecessary casts to int32_t from int16_t.
