Introduce new tests to capture the licensing discrepancies in the source

[shahsb]

The existing source code was having multiple files with openssl license instead of apache license 2.0 which is getting fixed via PR - https://github.com/openssl/openssl/pull/23576

But, this doesn't guarantee that all files in our code base will be future proof and comply to it. Also, there is high probability that newer files getting added may also miss such cases.
