Fix compilation warnings in libvpx (-Wunused-function)

Currently, there are 27 warnings saying:
> ../../third_party/libvpx_new/source/libvpx/vp9/encoder/vp9_denoiser.h:63:12:\
> warning: 'total_adj_strong_thresh' defined but not used [-Wunused-function]

It's because |total_adj_strong_thresh| is defined as static function in .h file.
So warning will appear in any file that includes the header but does not use
the function.

The suggested solution is to declare the static function as inline.
