apollo_batcher: make versioned constants override optional

[itamar-starkware]

TL;DR

Made versioned_constants_overrides an optional field in both BlockBuilderConfig and StatefulTransactionValidatorConfig.

What changed?

• Changed versioned_constants_overrides from a required field to an optional field (Option<VersionedConstantsOverrides>) in both BlockBuilderConfig and StatefulTransactionValidatorConfig
• Updated the default implementations to use Some(VersionedConstantsOverrides::default()) to maintain backward compatibility
• Modified VersionedConstants::get_versioned_constants() to accept an Option<VersionedConstantsOverrides> parameter
• Updated the implementation to use the latest constants when None is provided
• Updated all callers to handle the new optional parameter
• Added appropriate schema entries for the optional field

        versioned_constants_overrides: Option<VersionedConstantsOverrides>,
    ) -> Self {
        match versioned_constants_overrides {

Since both branches (some/none) end up calling Self::latest_constants().clone(), consider doing that once before. (non-blocking)
