[IMP] account_check_printing: make check printing generic

Now, if user intends to add a check layout for it's own country then he/she
will need to define a layout template and a report action associated to it.
The xmlID(s) of this report action(s) needs to set as key of
'account_check_printing_layout' selection field after redifining
it in it's own module.

Refer l10n_{ca/us}_check_printing modules.
