Implement contract verification logic for Tact and FunC

[rahulyadav-57]

Check verification status

• Determine if the contract has already been verified.
• Prevent redundant verification processes by identifying pre-verified contracts.

Collect contract files and build configuration

• Gather necessary contract files and build configurations.
• Push these to the backend of the TON contract verifier.

Handle backend response

• Receive a msg cell from the backend.
• Pass the received msg cell to the contract registry of the TON verifier for further processing.

Upon completing the final step, the contract will be successfully verified. You can view the verification results on verifier.ton.org or any TON explorer of your choice.

@rahulyadav-57 Please fill the body of this issue. It's unclear what logic will it implement, and thus how long will it take.
