perf(go): improve go core library test validators to improve test validation

[haseeb-mhr]

What

1. Added handling for form/Query Multipart parameters.
2. Now, the following body matcher will match response bytes instead of data object matching. These functions mainly cause the failure of test cases due to issues such as extra bytes being ignored when bytes are converted into objects, leading to failure during response matching:
   A. RawBodyMatcher
   B. KeysBodyMatcher
   C. KeysAndValuesBodyMatcher

Why

During the implementation of handling Datetime Format cases in the OAF implementation, I identified a loophole in the test validation process of go core library.
This issue affects the accuracy and reliability of the tests generated for the Go SDKs, potentially leading to incorrect validation of Go SDKs tests. It is crucial to address this issue promptly to ensure the correctness of the generated tests and the overall functionality of the Go SDKs.

Please review the comments.

General Comments:

• How was this tested?
• I appreciate the small size of the commits
• Does byte matching accurately reflect the kind of testing we want to do? It's good for contract testing but are we not going to test unmarshalling and marshalling? What about models?
• Could we have solved some of these issues by changing api-tester?
