Move Account Validity callbacks to a dedicated file

Spreading module callback registration across the codebase is both a bit
messy and makes it unclear where a user should register callbacks if
they want to define a new class of callbacks.

Consolidating these under the synapse.module_api module cleans things up
a bit, puts related code in the same place and makes it much more
obvious how to extend it.
