ci/bin: Print a summary list of dependency and target jobs

We already print all the detected target jobs from regex and its
dependencies. But for more complex regexes the list can be cumbersome,
and an aggregate list of dependencies and targets can be more value, so
add these prints as well.

This is what looks like:

```
Running 10 dependency jobs:
 alpine/x86_64_lava_ssh_client, clang-format, debian-arm64,
 debian-testing, debian/arm64_build, debian/x86_64_build,
 debian/x86_64_build-base, kernel+rootfs_arm64, kernel+rootfs_x86_64,
 rustfmt

Running 15 target jobs:
 a618_gl 1/4, a660_gl 1/2, intel-tgl-skqp, iris-amly-egl, iris-apl-deqp
 1/3, iris-cml-deqp 1/4, iris-glk-deqp 1/2, iris-kbl-deqp 1/3,
 lima-mali450-deqp:arm64, lima-mali450-piglit:arm64 1/2,
 panfrost-g52-gl:arm64 1/3, panfrost-g72-gl:arm64 1/3,
 panfrost-t720-gles2:arm64, panfrost-t860-egl:arm64, zink-anv-tgl
```
