Make each test lambda to be defined as a DEFUN %TEST-<NAME>. 

This accomplishes the goal of making M-. work in Slime, as well as fixing v
key in SLDB to correctly go the source

When using the `:compile-at :run-time` default, v key goes to just top of the function, because test body is dynamically compiled with (COMPILE), but if `:compile-at definition-time` is used, it goes to the exact line, with debug 3

All FIVEAM tests continue to pass.
