internal/impl: refactor MessageInfo

Changes made:
* Move MessageInfo.{methods,extensionFieldInfosMu,extensionFieldInfos}
to the coderMessageInfo type since they are fields all related to the
fast-path implementation, which is what the coderMessageInfo is for.
* Rename message_field.go -> message_reflect_field.go to make it obvious
from the file name that this only deals with the reflection implementation.
* Rename message_test.go -> message_reflect_test.go.
* Move reflection-specific implementation functions from message.go
to message_reflect.go. The intention is to make it such that message.go
is the entry point to message implementations and is agnostic towards
whether we are implementing reflection or the table-driven fast path.

Overall, there is no semantic changes. Just code movement.
