meta: handle multiple implementation registration

Browse source 
First check that we can actually register the implementation before
making a GstMetaInfo. If we can't register we would otherwise end
up with an undefined type and an invalid GstMetaInfo.

It's possible that type registration fails because another metadata
with the same implementation name was already registered.
