reflect/protoregistry: panic upon registration conflicts

In this CL, we switch the behavior of registration conflicts
from simply logging a warning to panicking.
This is a change that we have warned about ever since
the release of v1.20.0 in 2020-03-02.

For users that have not fixed their dependencies or are unable to,
they may set the GOLANG_PROTOBUF_REGISTRATION_CONFLICT environment
to "warn" in order to obtain the prior behavior of simply logging
and ignoring subsequent conflicts (first wins).
