lazily registers standard codecs

the attached patch seems to work ok with my system. it registers standard
codecs when on first call to `EncodingScheme.create()`, and it also exposes
`EncodingScheme.registerStandardCodecs()` function, which can be called to
manually register standard codecs if it is necessary in some other module ctor.

it is safe to call `EncodingScheme.registerStandardCodecs()` multiple times,
and from multiple threads.

this patch solves issue 16291 for the time being, until the proper fix for
cycle detection in module ctors isn't complete.
