add accelerate to load models with smaller memory footprint (#361) * add accelerate to load models with smaller memory footprint * remove low_cpu_mem_usage as it is reduntant * move accelerate init weights context to modelling utils * add test to ensure results are the same when loading with accelerate * add tests to ensure ram usage gets lower when using accelerate * move accelerate logic to single snippet under modelling utils and remove it from configuration utils * format code using to pass quality check * fix imports with isor * add accelerate to test extra deps * only import accelerate if device_map is set to auto * move accelerate availability check to diffusers import utils * format code Co-authored-by: Patrick von Platen <patrick.v.platen@gmail.com>
