Currently, there's no good way to test for the presence of set_memory_ro/rw/x/nx() helpers implemented by archs such as x86, arm, arm64 and s390. There's DEBUG_SET_MODULE_RONX and DEBUG_RODATA, however both don't really reflect that: set_memory_*() are also available even when DEBUG_SET_MODULE_RONX is turned off, and DEBUG_RODATA is set by parisc, but doesn't implement above functions. Thus, add ARCH_HAS_SET_MEMORY that is selected by mentioned archs, where generic code can test against this. This also allows later on to move DEBUG_SET_MODULE_RONX out of the arch specific Kconfig to define it only once depending on ARCH_HAS_SET_MEMORY.
