Output min_sdk_version to snapshot

The min_sdk_version was added to the java_import in Tiramisu. This
change will propagate the min_sdk_version set on a java_library to the
java_import snapshot. If possible the min_sdk_version will be resolved
into a numerical version to ensure consistent behavior across build
releases.

Bug: 260560424
Test: m nothing
      BUILD_NUMBER=fixed packages/modules/common/build/mainline_modules_sdks.sh
      # Ran above before and after this change and made sure that only
      # Tiramisu, UpsideDownCake and latest were changed and those changes
      # were the addition of a min_sdk_version property.
      #
      # Ran the following command in tm-mainline-prod:
      #     lunch cf_x86_64_phone-userdebug
      #     m ART_MODULE_BUILD_FROM_SOURCE=false nothing`.
      #
      # It failed with:
      #     module "prebuilt_okhttp-norepackage" variant "android_common": should support min_sdk_version(33) for "AdServicesApk": min_sdk_version is not specified.
      #
      # Unpacked the Tiramisu art snapshot generated with this change into
      # tm-mainline-prod and reran the previous command and it succeeded.
