llext: enable tristate Kconfig options
kconfiglib.py has a hard dependency on CONFIG_MODULES to support 'm'
values for tristate Kconfig options. It's a logical companion for
but can also be used with other configurations.

+ help
+ Zephyr supports dynamically loadable code, e.g. using llext. Code,
+ that can either be built as a part of the system image or as a
+ loadable extension, can use tristate Kconfig options. For this to work
+ the CONFIG_MODULES option must be enabled by the project. Enabling
+ this option alone doesn't change the build on its own, it only allows
+ using 'm' for tristate Kconfig options.
