arch: Rename CONFIG_DEBUG_RODATA and CONFIG_DEBUG_MODULE_RONX

Browse source 
Both of these options are poorly named. The features they provide are
necessary for system security and should not be considered debug only.
Change the names to CONFIG_STRICT_KERNEL_RWX and
CONFIG_STRICT_MODULE_RWX to better describe what these options do.
