Create java_api_contribution_import from sdk_library_import

This change modifies sdk_library_import so that it directly creates
java_api_contribution per api scope. The module creates api_contribution
module for api scopes where the api file is specified.

Test: m nothing && MODULE_BUILD_FROM_SOURCE=false m nothing
--build-from-text-stub and inspect ninja dependency of java_api_library
