Reland "[idk][build] Build less for the in-tree IDK"

This is a reland of commit 00527f7a7c9582805fb5fa860266da56631e7060

This version temporarily adds a dependency a non-SDK dependency on the
reduced "core" collection to the in-tree IDK so that the core manifest
is always generated at the same time as the in-tree IDK. This will allow
these dependencies to be eliminated separately without blocking this
large refactor.

Original change's description:
> [idk][build] Build less for the in-tree IDK
>
> Create separate IDK build graphs for the IDK used in-tree (by the Bazel
> in-tree SDK and ffx tests) and the official IDK distributed to partners.
> This decreases the build graph for most developers.
>
> "//sdk:bazel_in_tree_idk" and "//sdk:sdk" now depend on the in-tree
> graph. This avoids building unneeded targets when, for example,
> assembling with the Bazel SDK.
>
> "final_fuchsia_idk.exported" depends on the complete IDK graph, which is
> now called "fuchsia".
>
> The template named "idk_rules" implements the common logic for the two
> graphs, which provide the specific targets to include when instantiating
> the template.
>
> Remove ":sdk_source_set_list" from "//sdk" since it is already a direct
> dependency of "//:api" and would otherwise pull in the full IDK.
>
> The same set of host tools are included in a default build, but tools
> not needed as part of the SDK build are not included in the in-tree IDK.
> This allows these tools to be built in parallel with targets that depend
> on the IDK and SDK.
>
> Also partially fix the dependency checking that triggers sub-build
> rebuilds by adding a non-SDK deps in the main build on targets that are
> produced for the IDK only in sub-builds. Packages are the remaining gap.
