openvino: [Good first issue] [API CONFORMANCE] [CPU PLUGIN] Support unsupported property OPTIMAL_BATCH_SIZE in CPU plugin

Description:

API conformance suite is OV validation tool checks a plugin conditions from API implementation perspective. ov_plugin/OVCheckMetricsPropsTests_ModelDependceProps.ChangeCorrectDeviceProperties/target_device=CPU_properties=* fails on CPU Plugin

Unsupported properties:

RO (ReadOnly):

• OPTIMAL_BATCH_SIZE

How to reproduce:

1. Build the OV using -DENABLE_TESTS=ON -DENABLE_FUNACTIONAL_TESTS=ON -DENABLE_INTEL_CPU=ON
2. Build ov_api_conformance_tests target

 ./ov_api_conformance_tests --gtest_filter="ov_plugin/OVCheckMetricsPropsTests_ModelD
ependceProps.ChangeCorrectDeviceProperties/target_device=CPU_properties={OPTIMAL_BATCH_SIZE*"

How to fix

support OPTIMAL_BATCH_SIZE in CPU plugin, set 1 as the default value, return the default value. Example PR https://github.com/openvinotoolkit/openvino/pull/22007
