Add gpu_device access to isolated_compute_app

Currently all apps except `isolated_app_all` already have this access. Since `isolated_compute_app` is a special case of `isolated_app` with relaxed security restrictions to allow hardware acceleration use cases - it is safe to extend the same access as rest of the apps(system/sepolicy/private/app.te;l=389-394), to `isolated_compute_app`.

Test: tested with latest build, gpu inference works without any permission denials.
