[Good First Issue][NNCF][Tests]: Refactor weights compression tests into a template tests.

[daniil-lyakhov]

Context

Majority of the NNCF PTQ tests are using templates: for example tests for Fast Bias Correction or MinMax algorithm.
The structure is following: there is a template file like this, and each backend implements abstract methods of the template file like this.

What needs to be done?

The task is to:

1. Introduce Template tests(class TemplateTestWeightsCompression) for weights compression in the test_weights_compression.py file in this directory: https://github.com/openvinotoolkit/nncf/tree/develop/tests/cross_fw/test_templates
2. Refactor this files
   ** https://github.com/openvinotoolkit/nncf/blob/develop/tests/torch/ptq/test_weights_compression.py
   ** https://github.com/openvinotoolkit/nncf/blob/develop/tests/torch/fx/test_compress_weights.py
   to implement the template.
   The template should implement following common tests:

• test_compress_weights
• test_compress_shared_weights / test_compress_weights_shared_weights
• test_compress_weights_functional_model / test_compress_weights_functional_model
• test_raise_error_with_unsupported_params_for_int8
• test_raise_error_with_unsupported_params_for_int4
• test_raise_error_with_not_int8
• test_raise_error_for_statistics_caching
• test_get_dtype_attribute_of_parameter
• test_model_devices_and_precisions

Please use this two template files as a reference:
https://github.com/openvinotoolkit/nncf/blob/develop/tests/torch/fx/test_fast_bias_correction.py
https://github.com/openvinotoolkit/nncf/blob/develop/tests/torch/ptq/test_fast_bias_correction.py
