There is currently no in-tree tool to manipulate Kconfig settings in a
non-interactive way similar to the Linux scripts/config utility [1].
Such tooling is useful when building Xen via external build systems (e.g.,
Yocto) and can also simplify custom CI configuration.

This series imports the Linux scripts/config helper and integrates it
into an existing Xen automation script.

Example of usage:

  ./xen/scripts/config --file xen/.config -y FOO -n BAR -y BAZ

Patch 1 imports scripts/config from Linux (based on v6.19-rc5) [1].
Patch 2 drops the -m option, since Xen does not support modules.
Patch 3 adds convenience flags -y (set to yes) and -n (set to no).
Patch 4 performs minimal integration into existing Xen build system.
