Select stub/impl per apex variant
Create a select statement for every api_domain a library could be
included in. The stub/impl
selection heuristics per apex domain are
1. If dep has stubs and the api domain appears in dep's apex_available, use
impl
2. If dep has stubs and the api domain does not appear in dep's
apex_available, use stubs
(Category 3: If dep does not have stubs and the apex does not appear in
dep's apex_available, then a separate apex_available validation in Bazel
will emit an error).
Platform variants have been special-cased for now to use equality of
apex_available for stub/impl selection
Test: go test ./bp2build
