The generated Bazel workspace will only contain api specific targets. This is feasible since these targets do not have any cross dependencies with the targets in the bp2build workspace The advantages of a new mode are 1. Does not pollute bp2build workspace with api targets 2. Does not block api targets with the current allowlist conversion mechansims in bp2build (In the future we might want to combine these two workspaces) A Soong module type will generate a Bazel target if it implements ApiProvider interface Test: m apigen Test: m nothing Change-Id: I69c57ca6539f932e0ad554ce84a87fb7936fdba0
