soundtrigger: Apply clang-format to 2.0 default implementation

The implementation needs to be updated to become extensible.
The current coding style is not consistent with the style
required for hardware/interfaces.

Reformatted with:
   clang-format -style=file -i <...>/SoundTriggerHalImpl.*
No manual changes.

Bug: 68823037
Change-Id: I5f5cbb599190a515dec8afe9026ca835b8fd20fa
Test: make
