internal/impl: move legacy files into impl

The internal/legacy package was originally separated out from internal/impl
to avoid a cyclic dependency on descriptor proto. However, the dependency
that legacy has on descriptor has long been dropped such that we can
now merge the two packages together again.

All legacy related logic are in a file with a legacy prefix.
