Accelerate support for GLM

[Larry Law]

Hi, I've made a PR to support accelerate for GLM. Can you help review it?

Example code:

from transformers import AutoModelForSeq2SeqLM

device_map={'glm.word_embeddings': 0,
 'glm.transformer.embedding_dropout': 0,
 'glm.transformer.position_embeddings': 0,
 'glm.transformer.block_position_embeddings': 0,
 'glm.transformer.layers.0': 0,
 'glm.transformer.layers.1': 0,
 'glm.transformer.layers.2': 0,
 'glm.transformer.layers.3': 0,
 'glm.transformer.layers.4': 0,
 'glm.transformer.layers.5': 0,
 'glm.transformer.layers.6': 0,
 'glm.transformer.layers.7': 0,
 'glm.transformer.layers.8': 0,
 'glm.transformer.layers.9': 0,
 'glm.transformer.layers.10': 0,
 'glm.transformer.layers.11': 0,
 'glm.transformer.layers.12': 0,
 'glm.transformer.layers.13': 0,
 'glm.transformer.layers.14': 0,

 'glm.transformer.layers.22': 0,
 'glm.transformer.layers.23': 0,
 'glm.transformer.layers.24': 0,
 'glm.transformer.layers.25': 0,
 'glm.transformer.layers.26': 0,

# ours
model_name_or_path = "THUDM/glm-10b-chinese"
model = AutoModelForSeq2SeqLM.from_pretrained(model_name_or_path,
                                    trust_remote_code=True, 
                                    revision="6adb492",
                                    device_map=device_map,
                                    load_in_8bit=True,
                                    )
model.eval()

Can you also help me test if device_map=auto works? That is,

from transformers import AutoModelForSeq2SeqLM
model_name_or_path = "THUDM/glm-10b-chinese"
model = AutoModelForSeq2SeqLM.from_pretrained(model_name_or_path, trust_remote_code=True, revision="6adb492", device_map="auto")

Thank you!
