[nrf fromtree] soc: nordic: uicr: Move GEN_UICR options into the main Zephyr tree

I initially added the GEN_UICR options to the gen_uicr image's Kconfig
tree only to not pollute the main tree.

But there is a lot of useful help text in the GEN_UICR option's
Kconfig file that I would like users to be able to read/reference from
the docs.

To not increase the complexity of the Kconfig doc generator, we add
the GEN_UICR options to the main tree and have them all be disabled
for builds other than the gen_uicr image.

Being in the main tree has the added benefit of being recognzied by
the compliance checker.
