[MOV] hr_expense: split data to separate mail data from other data

It is simpler to have data split by main model or application like we
already do for models and views. It allows to easily have an overview
of data a module holds.

As we will work on mail related data like adding activities or tweaking
subtypes and templates, having them all in a single file and not lost
between other data helps finding and working with it.

This commit only moves code. No functional change should occur.
