Summary: This patch removes the bulk of the handling of the `__tgt_offload_entries` out of the plugins itself. The reason for this is because the plugins themselves should not be handling this implementation detail of the OpenMP runtime. Instead, we expose two new plugin API functions to get the points to a device pointer for a global as well as a kernel type. This required introducing a new type to represent a binary image that has been loaded on a device. We can then use this to load the addresses as needed. The creation of the mapping table is then handled just in `libomptarget` where we simply look up each address individually. This should allow us to expose these operations more generically when we provide a separate API.
