reflect/protoregistry: add compile-time opt-out for registration conflicts

The next release of this module will panic on registration conflicts.
While we have been warning that this will become a fatal error for about
a year now, it's almost certainly the case that some users still have
ambiguous registrations.

In addition to the GOLANG_PROTOBUF_REGISTRATION_CONFLICT environment variable,
also define a linker-initialized variable that users can set.
