We use protected visibility for almost everything with offloading. This is because it provides us with the ability to read things from the host without the expectation that it will be preempted by a shared library load, bugs related to this have happened when offloading to the host. This patch just makes the `exec_mode` global generated for each plugin have protected visibility. Reviewed By: jdoerfert Differential Revision: https://reviews.llvm.org/D135285
