x86/ftrace: enable dynamic ftrace without CONFIG_MODULES
Dynamic ftrace must allocate memory for code and this was impossible
without CONFIG_MODULES.
With execmem separated from the modules code, execmem_text_alloc() is
available regardless of CONFIG_MODULES.
Remove dependency of dynamic ftrace on CONFIG_MODULES and make
CONFIG_DYNAMIC_FTRACE select CONFIG_EXECMEM in Kconfig.
