Add new global attribute: applicable_licenses
- Package level default with default_applicable_licenses
- guarded by --incompatible_applicable_licenses (default true for Blaze, false for Bazel)
Import features:
- applicable_licenses is not configurable. Software does not get a different
license in different environments. The license it is provided under dictates
what type of environments you may use it in.
- applicable_licenses is exempt from compatible_with checks. For the same
reason.
Since there is currently no actual behavior within Bazel, the test cases
are located with @rules_license. In the future, we will add provider
checking to applicable_licenses. (b/148601291), at which point there
must be positive and negative tests alongside the Bazel code.
