PR 1991/cpukit - attr.c (really mode code) warning rework

This PR was about a warning for no previous prototype for
rtems_interrupt_level_attribute. This method exists (like
a few others) to have real bodies for Classic API services
implemented as macros. These macros are not available from
anything but C and C++. The most explicit use was in the Ada
binding but these would be needed from assembly language
or any other non-C based language.

On top of needing a prototype, the methods were misnamed.
They were related to modes.  This renames them, moves the
file, fixes test code, etc.
