userspace: remove APPLICATION_MEMORY feature

Browse source 
This was never a long-term solution, more of a gross hack
to get test cases working until we could figure out a good
end-to-end solution for memory domains that generated
appropriate linker sections. Now that we have this with
the app shared memory feature, and have converted all tests
to remove it, delete this feature.

To date all userspace APIs have been tagged as 'experimental'
which sidesteps deprecation policies.
