feat: Add defaults for policy and block tracker options

[FrederikBolding]

Explanation

Port defaults for maxRetries, maxConsecutiveFailures and circuitBreakDuration from the clients into core. This also enables us to make getRpcServiceOptions optional. Also brings in defaults for pollingInterval and retryTimeout.

Checklist

• I've updated the test suite for new or updated code as appropriate
• I've updated documentation (JSDoc, Markdown, etc.) for new or updated code as appropriate
• I've communicated my changes to consumers by updating changelogs for packages I've changed
• I've introduced breaking changes in this PR and have prepared draft pull requests for clients and consumer packages to resolve them

Note

Medium Risk
Changes default RPC retry/circuit-break and block polling behavior for all network clients; consumers who omitted getRpcServiceOptions or depended on prior client-only defaults may see different failover and unavailable timing.

Overview
Network clients now ship built-in RPC and block-tracker tuning so callers no longer have to supply getRpcServiceOptions for standard retry/circuit behavior.

getRpcServiceOptions is optional on NetworkController and network client creation paths. When omitted, create-network-client merges @metamask/controller-utils defaults into each RPC endpoint: maxRetries 3, circuitBreakDuration 30s, and maxConsecutiveFailures 12 on the primary URL vs 40 on failover URLs (higher threshold so QuickNode-style activation does not trip the circuit too early). Custom overrides from getRpcServiceOptions still win via spread after those defaults.

Block tracker defaults are set in the same layer: 20s pollingInterval and retryTimeout (still 1s for custom networks under IN_TEST). Tests were updated for the new retry counts and circuit timing (e.g. 12 vs 40 mocked failures, 30s timer advance).

Do we consider this breaking?

Each client already uses these values FWIW.

I don't think so. It doesn't require any changes in consumers.
