Summary: For our offloading entries, we currently store all the string names of kernels that the runtime will need to load from the target executable. These are available via pointer in the `__tgt_offload_entry` struct, however this makes it difficult to obtain from the object itself. This patch simply puts the strings in a named section so they can be easily queried. The motivation behind this is that when the linker wrapper is doing linking, it wants to know which kernels the host executable is calling. We *could* get this already via the `.relaomp_offloading_entires` section and trawling through the string table, but that's quite annoying and not portable. The follow-up to this should be to make the linker wrapper get a list of all used symbols the device link job should count as "needed" so we can handle static linking more directly.
