Include depends on info when generating konfig rst list (IDFGH-12439)

[ESP-Marius]

When we generate the kconfig option list we do not include the depends on information.

This might confuse some users as seen e.g. in espressif/esp-idf#7583

I think we should consider also including this depends on (and maybe also select) in the gen_kconfig_doc.py output.
