[OpenVINO backend] Support numpy.log10

[darshil929]

I have added support for numpy.log10 in OpenVINO backend by:

1. Implementing log10(x) as log(x)/log(10) using available operations from OpenVINO
2. Remove numpy.log10 from excluded_concrete_tests.txt file

About implementation:

• I followed same pattern like other math functions in backend
• Added handling for proper type conversion with integral types
• Tests pass successfully on CPU environment

Related to: openvinotoolkit/openvino#29486

@rkazants

Sir, I've fixed the log function to properly handle type conversion for integral inputs, similar to the log10 implementation. The test_log is now passing successfully.
