Add missing api_imports module
Soong C API import looks for a module called `api_imports` and if
present, builds vendor against stubs presented by it instead of the
LLNDK stubs that originate from that tree.
Test: multitree_build vendor/nothing
Test: grep "\-Iout/api_surfaces"
out/trees/vendor_aosp_cf_arm64_phone/soong/build.ninja
(returns matches which indicates that vendor is compiling against
headers in the generated api_surfaces dir)
