lineage: products: Un-break SDK addon

- Fixes error while building
  Trying to build sdk_addon, but product 'vendor/lineage/build/target/product/lineage_sdk_phone_x86_64.mk' does not define one
- Move gsi_release.mk to gsi_tv_arm*.mk. SDK and x86* targets won't build.
- Set TARGET_SUPPORTS_64_BIT_APPS for x86_64 gsi to support both arch apps.
