* chore(deps): upgrade stardoc
This uses the Bazel 7 'starlark_doc_extract' rule which our docsite expects for slurping data.
* chore: stardoc setup in WORKSPACE too
* chore: skip stardoc on bazel 6 in cases where the legacy extractor produces different docstrings
* feat: add a helper for rules to work with resource_sets
This API is poorly designed and needs some help to let rule users pick a value in cases that they aren't also the rule author
* chore: add some cpu resource_set values as well
