feat: support sync when update gateway proxy

[ronething]

• Adjust the leader_election related configurations to prevent leader election loss due to adc execution timeouts
• Add a mutex lock to adcExec to prevent unforeseen issues caused by parallel execution of adc

Pull Request Overview

This PR adds support for syncing resources when the GatewayProxy is updated by adjusting leader election settings, adding mutex locks to ADC execution, and updating various e2e tests to verify the changes.

• Updated e2e tests for Ingress, HTTPRoute, and Consumer to validate sync behavior after updating the GatewayProxy.
• Modified the ADC provider by introducing an execLock and refactoring the handling of ADC configuration values.
• Updated controller watchers and indexers to include GatewayProxy changes and improved leader election configuration.
