[Feature Request] Add ABI parsing support for script bytecode

[WGB5445]

🚀 Feature Request Description

Currently, when a script payload is passed in JSON format, its parameters are represented as classes, which cannot be directly serialized. Although it’s possible to work around this by using a special serialization format — for example, by sending the BCS-encoded data — this still isn’t an ideal solution.

const BytecodeTransaction = {
    "bytecode": "0x.....",
    "typeArguments": [],
    "functionArguments": [
        new U64(627),
        new Bool(true),
        new U64(100000),
        new Bool(false),
        new U64(100),
        new U64(100),
        new U64(0),
        new U64(0),
        new Bool(true)
    ]
}

So, would it be possible to introduce a simple way to parse the bytecode format and extract its ABI, allowing us to reuse the existing ABI parsing logic used for entry functions?
