Introduce a kernel-6.18-shared-configs package that ships the base
Bottlerocket kernel configuration fragments (config-bottlerocket and
its per-architecture variants) and installs them into the build
sysroot.
Every 6.18-based kernel can then consume these fragments at build time
via a BuildRequires rather than carrying its own copy. Convert
kernel-6.18 to pull them from the shared package: drop its local
config-bottlerocket{,-x86_64,-aarch64} sources, add the build
dependency, and merge the fragments from %{kernel_configdir} in %prep.

add a new flavor of the 6.18 kernel to support booting microvms such as Firecracker. This flavor reuses the same source, patches and Bottlerocket config fragments as kernel-6.18, adds config-microvm to build the virtio transport, network and vsock drivers in, and ships bzImage or vmlinuz.efi depending on architecture Include a new config-microvm for setting configuration options specific to guests so a microvm guest can boot a minimal virtio device model.

^ force pushes extract out the shared custom kconfigs to a new package, |
latest-kernel-full-config.sh reconstructed each package directory from the SRPM's majorminor version (6.18.51 -> 6.18), so two packages that share a majorminor (kernel-6.18 and kernel-6.18-microvm) could not be told apart and the microvm flavor never got its own configuration generated. Pass the actual package directory through merge/validate instead. Signed-off-by: Gavin Inglis <giinglis@amazon.com>

Description of changes:
Add
kernel-6.18-microvmto the kernel-kit.kernel-6.18-microvmis a flavor ofkernel-6.18with a config overlay so a microvm guest can boot a minimal virtio device model.CONFIG_VIRTIO_MMIO=y,CONFIG_VIRTIO_BLK=y, vsock, dm-verity, erofs, serial are built in.kernel-6.18ships neuron/EFA/GPU/full module set;kernel-6.18-microvmstrips much of that.The source RPM and custom patches are identical to
kernel-6.18. These changes also include updates to the config generation for this new kernel package, including diff checks to ensure the 6.18 specific configs don't drift between this new package andkernel-6.18.For an annotated diff of this new
kernel-6.18-microvmvs.kernel-6.18, see https://gist.github.com/ginglis13/6298e4c5a8c2451cabf5059bc2f3b718Testing done:
