chore: programmed condition and conformance

[mlavacca]

What this PR does / why we need it:

The GatewayProgrammedCondition and ListenerProgrammedCondition conditions are set on the Gateway. Furthermore, the tests GatewaySecretReferenceGrantAllInNamespace and GatewaySecretReferenceGrantSpecific are fixed. Only GatewaySecretReferenceGrantAllInNamespace has been re-enabled because of an upstream issue that makes the tests fail: kubernetes-sigs/gateway-api#1745.

Which issue this PR fixes:

Part of #3305
