ApiServerSource should set Status.Ce Attributes based on the mode

[capri-xiyue]

Describe the bug
Now ApiServerSourcewill set in the status the 6 EventTypes. It should only set the three that correspond to the mode. Say you configure the mode to be ref, we should just set the add, update, delete event types that belong to ref. Not the ones from resource

Expected behavior
ApiServerSource should set Status.Ce Attributes based on the mode

To Reproduce
Create a ApiServerSource and check the Status.Ce Attributes

[capri-xiyue]

The EventType set in the status should be based on the mode of ApiServerSource
