Deprecate _get_compression_options

[echarlaix]

In this PR :

• we enable the ov_config argument for all OVModels (previously reserved to OVModelForCausalLM) in order to give the possibility to pass any quantization_config
• we deprecate the _get_compression_options method

@echarlaix, what is the plan for CLI? Will we have all the granular options exposed to the user, e.g. --bits, --sym, --dataset, etc.

Yes I'm working on a PR to deprecate compression_options and compression_ratio, will then do a second PR to deprecate add --bits, --sym parameters
