[7.1.0] Fix bazel fetch by replacing query with cquery for underlying implementation

[meteorcloudy]

Context:

• Traditional query relies on the initial loading phase of the build, this lacks the context of build configurations (flags, select() logic), leading to potentially inaccurate or over-inclusive dependency listings.

• cquery executes after the analysis phase, where Bazel has resolved configurations and determined how options influence target definitions. This allows cquery to provide the dependencies truly needed for a build under the current settings.

Considering these differences, I'm updating fetch target logic to rely on cquery instead. This ensures that all necessary repositories are fetched for an offline build while avoiding potential over-fetching

While backporting dfbb3ce I had to also backport 81e1333, but I got the above test failure. Is there some additional change missing?

[gregestren]

I'm not sure why that test is failing. That test only triggers when cquery runs with the new --experimental_explicit_aspects flag, which is still being baked in.

I recommend just disabling the test with a TODO to fix. I'm happy to dig into why it's failing but that'll take some more time.

@Wyverald @meteorcloudy checks are passing now, but could you take a look at the CLA issue / force merge?
