module: Move module_enable_x() and frob_text() in strict_rwx.c
Move module_enable_x() together with module_enable_nx() and
module_enable_ro().
Those three functions are going together, they are all used
to set up the correct page flags on the different sections.
As module_enable_x() is used independently of
CONFIG_STRICT_MODULE_RWX, build strict_rwx.c all the time and
use IS_ENABLED(CONFIG_STRICT_MODULE_RWX) when relevant.
