Previous support for device memory allocators used a single free routine and did not provide the original kind of the allocation. This is problematic as some of these memory types required different handling. Previously this was worked around using a map in runtime to record the original kind of each pointer. Instead, this patch introduces new free routines similar to the existing allocation routines. This allows us to avoid a map traversal every time we free a device pointer. The only interfaces defined by the standard are `omp_target_alloc` and `omp_target_free`, these do not take a kind as `omp_alloc` does. The standard dictates the following: "The omp_target_alloc routine returns a device pointer that references the device address of a storage location of size bytes. The storage location is dynamically allocated in the device data environment of the device specified by device_num." Which suggests that these routines only allocate the default device memory for the kind. So this has been changed to reflect this. This change is somewhat breaking if users were using `omp_target_free` as previously shown in the tests.
