When building different distros for the same machine (e.g.,
phyboard-mira-bullseye and phyboard-mira-bookworm), files with the same
name (e.g, DTB files) might be deployed to the same location and this
causes a build error.
Use DISTRO- and KERNEL-dependent deploy directory.
Also fix paths in installer and testsuite.
Fixes test_dtb_deploy_distros testcase:
ERROR: mc:phyboard-mira-bookworm:isar-image-base-1.0-r0 do_copy_boot_files: The recipe isar-image-base is trying to install files into a shared area when those files already exist. Those files and their manifest location are:
NOTE: recipe isar-image-base-1.0-r0: task do_copy_boot_files: Failed
build/tmp/deploy/images/phyboard-mira/imx6q-phytec-mira-rdk-nand.dtb
(not matched to any task)
Please verify which recipe should provide the above files.

Task do_copy_boot_files deploys DTB files into the same location for
different images (e.g., isar-image-base and isar-image-ci). This causes
a build error.
do_copy_boot_files is called once for every image recipe while dtb
files belong to the kernel which is the same for both images. Performing
dtb deployment once for the same kernel solves the issue.
Introduce `kernel-deploy` recipe responsible for extracting the DTBs and
kernel from the linux-image package and deploying them. The kernel
package is now installed into sbuild chroot. This is achieved via the
respective dependency of `kernel-deploy` recipe.
Fixes test_dtb_deploy_images testcase:
ERROR: mc:phyboard-mira-bookworm:isar-image-base-1.0-r0 do_copy_boot_files: The recipe isar-image-base is trying to install files into a shared area when those files already exist. Those files and their manifest location are:
build/tmp/deploy/images/phyboard-mira/imx6q-phytec-mira-rdk-nand.dtb
(not matched to any task)
Please verify which recipe should provide the above files.

+### Move kernel and DTBs deployment from image recipe to kernel related one
+
+To prevent parallel conflicting artifacts deployment from the same kernel
+used by different images, move do_copy_boot_files() task logic from the image
+recipe to the separate one, which is once-per-kernel. With this aproach the
+deployment of any kernel artifacts will be performed only once per kernel.

+To left previous kernel image path per-image symlinks are now used.
+
+This deployment is implemented as separated recipe to be compatible both with
+custom and distro kernel types.
