Make bounded_visitor default bound configurable

[henrymai]

Steps to Reproduce Issue

Upon trying to perform a sui_tryMultiGetPastObjects on checkpoint 32260640, we get the following error:

RPC call sui_tryMultiGetPastObjects failed (1 retries remaining): ErrorObject { code: ServerError(-32000), message: "RPC call failed: Failure serializing object in the requested format: \"Deserialized value too large\"", data: None }
Pipe terminated: Err(Failed to process checkpoint: 32260640

Caused by:
    0: getting past objects
    1: Failed to process `sui_multiGetPastObjects`
    2: ErrorObject { code: ServerError(-32000), message: "RPC call failed: Failure serializing object in the requested format: \"Deserialized value too large\"", data: None }
    3: ErrorObject { code: ServerError(-32000), message: "RPC call failed: Failure serializing object in the requested format: \"Deserialized value too large\"", data: None }

I'm not sure exactly which object right now since our logs don't mention it.

However, upon digging through the code, it looks like a potential fix for this is to just allow the bounded_visitor default bound (or deserialization code path) to be configurable.

Here are some more details from tracing the error in the SUI codebase:

This is the error:

#[error("Deserialized value too large")]
OutOfBudget,

The error is returned in bounded_visitor.rs:debit() :

sui/crates/sui-types/src/object/bounded_visitor.rs

Line 72 in 0d2d137

Err(Error::OutOfBudget)

debit() is called while deserializing the struct.

The struct deserialization path just uses Self::default()

self.bound defaults to const MAX_BOUND: usize = 1024 * 1024;

Since we are running our own SUI node, a quick fix for this would be to make the default for self.bound configurable rather than using a hardcoded const, and then we can re-deploy the updated version with the appropriate configuration increasing the default bound.

Expected Result

Expect to be able to successfully retrieve the object history when using sui_tryMultiGetPastObjects.

Actual Result

SUI RPC node error in the description above.
