kallsyms, bpf: Move find_kallsyms_symbol_value out of internal header
Moving find_kallsyms_symbol_value from kernel/module/internal.h to include/linux/module.h. The reason is that internal.h is not prepared to be included when CONFIG_MODULES=n. find_kallsyms_symbol_value is used by kernel/bpf/verifier.c and including internal.h from it (without modules) leads into a compilation error: In file included from ../include/linux/container_of.h:5, from ../include/linux/list.h:5, from ../include/linux/timer.h:5, from ../include/linux/workqueue.h:9, from ../include/linux/bpf.h:10, from ../include/linux/bpf-cgroup.h:5, from ../kernel/bpf/verifier.c:7: ../kernel/bpf/../module/internal.h: In function 'mod_find': ../include/linux/container_of.h:20:54: error: invalid use of undefined type 'struct module' 20 | static_assert(__same_type(*(ptr), ((type *)0)->member) || \ | ^~ [...] This patch fixes the above error.
