I18n: Go over TIP_ and IFACE_ usages, change to RPT_ when relevant

The previous commit introduced a new `RPT_()` macro to translate
strings which are not tooltips or regular interface elements, but
longer reports or statuses.

This commit uses the new macro to translate many strings all over the
UI.

Most of it is a simple replace from `TIP_()` or `IFACE_()` to
`RPT_()`, but there are some additional changes:
- A few translations inside `BKE_report()` are removed altogether
  because they are already handled by the translation system.
- Messages inside `UI_but_disable()` are no longer translated
  manually, but they are handled by a new regex in the translation
  system.
