Adding aic-hw-version Compile Options Support

[abukhoy]

This pull request introduces compile-time options as kwargs, aic-hw-version support which takes value ai200 or 2.0.

These changes allow users to customize the compile Api according to their requirements.

Example:

from QEfficient import QEFFAutoModelForCausalLM
from transformers import AutoTokenizer

model_name = "gpt2"
model = QEFFAutoModelForCausalLM.from_pretrained(model_name, num_hidden_layers=2)

model.compile(prefill_seq_len=128, ctx_len=256, num_cores=16, num_devices=1, **{'aic-hw-version':'2.0'})

tokenizer = AutoTokenizer.from_pretrained(model_name)
model.generate(prompts=["Hi there!!"], tokenizer=tokenizer)

Can't we just pop the compiler_options and append to command like we are doing for other compiler options. That way code will be cleaner imo.

[abukhoy]

If we pop compiler options one by one, then number of lines will increase, and AIC compiler tool support many other options which would be limited.

I have made a little change to the _compile function of the base class by including some helper method. If it's not okay then I will revert it.
