tools: Remove shgen

All tools should be removed from the RTEMS source repository at some
point in time. Tools with a BSD-style license will be moved to the RTEMS
tools repository. Unfortunately, the shgen tool is GPL licensed.

Remove all uses of this tool from the code base. Replace generated files
with stub functions. If users of this BSP still exist, they can
reimplement the functionality using a BSD-style license.

Close #3443.
