Adding aic-hw-version Compile Options Support

[abukhoy]

This pull request introduces support for compile-time options via keyword arguments (kwargs), including the aic-hw-version parameter, which now accepts values "ai100" or "ai200". If no value is provided, the default is "ai100", representing the AI100 hardware.

These enhancements allow users to tailor the compile API to better suit their specific requirements.

Example Usage:

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': 'ai100'})

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

Note: Previously, the default value for aic-hw-version was "2.0", which implicitly referred to AI100. This value is now deprecated and replaced with the explicit "ai100" identifier.

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.

Is anything pending on this? I think we are good to merge this change.

Yes, the compiler changes need to be merged first before we proceed with adding this change to Qeff.
