Add ExcludeFromMcp() resource extension

[JamesNK]

Description

This PR adds a way for resources to opt-out of being included in AI results. When opted out, a resource won't be returned with list_resources, won't be a target of execute_resource_command, and no telemetry/consoles logs will be returned for it.

For example, adding frontendBuilder.WithOptOutAI() will exclude the frontend resource from all AI results.

Fixes #12504
