ci: add generic kernel check

This runs 'kconfig generate' for all archs that the generic kernels
support in order to make sure that kconfig-generic.toml changes are
valid for everything for the kernels it would apply to. This is meant
to catch kconfig changes that might introduce options that don't exist
on some kernel/arch combos or that might be missing other kconfig
dependencies.
