Added Post Quantum Server Testing Program

[Haseeb702]

Purpose

• To create a server side testing program to test signature generation time of post quantum and current algorithms

Changes

• Added ML-DSA-65, Falcon-512, RSA-4096, ECDSA-384 signature generation code
• Added a main file that runs 100 iterations of each algorithm with small and medium payloads
• Added a README

Minor suggestion and some questions:

• why is there a GenerateKey() for both Falcon and RSA tests but not for MLDSA and ECDSA?
• Why generate a new key for every test case for Falcon and RSA?
• Why generate the RSA key locally rather than creating/storing it in the KMS?
• Is the expectation that a key named mldsa and ecdsa with ML-DSA-65 and RSA-4096 respectively already created and stored in the KMS? If so, I recommend sharing the requirement/instructions about this on the README.

According to the internet (not official Go doc), you use uppercase if you are exporting the constant variable. Will you make changes to the variable names so they are consistent with the usage?

Thanks. I'll change the variable names to uppercase.
