Support injecting custom native codecs from Java.

Browse Source 
This CL extends our support for injecting native codecs such that
downstream users can create Java codecs that are backed by custom
native codecs.

After this CL, the Java codec interfaces expose
createNativeVideo{En,Decoder}() methods that may return a value
representing a pointer to the backing native codec. Previously,
a similar mechanism was used for the special case of non-public
Java codecs extending from the internal
WrappedNativeVideo{En,De}coder classes.

Tested: AppRTCMobile on Pixel XL and Pixel 2.
