[PATCH] kbuild: Show Kconfig fragments in "help"

> Doing a "make help" would show only hard-coded Kconfig targets and
> depended on the archhelp target to include ".config" targets. There was
> nothing showing global kernel/configs/ targets. Solve this by walking
> the wildcard list and include them in the output, using the first comment
> line as the help text.
> 
> Update all Kconfig fragments to include help text and adjust archhelp
> targets to avoid redundancy.
> 
> Adds the following section to "help" target output:
> 
> Configuration fragment targets (for enabling various Kconfig items):
>    debug.config         - Debugging for CI systems and finding regressions
>    kvm_guest.config     - Bootable as a KVM guest
>    nopm.config          - Disable Power Management
>    rust.config          - Enable Rust
>    tiny-base.config     - Minimal options for tiny systems
>    tiny.config          - Smallest possible kernel image
>    x86_debug.config     - Debugging options for tip tree testing
>    xen.config           - Bootable as a Xen guest
>    tiny.config          - x86-specific options for a small kernel image
>    xen.config           - x86-specific options for a Xen virtualization guest
