Use @All to inject ObjectMapperCustomizers

This way, we are sure they are sorted by @priority.
And they can still be sorted by #getPriority(), this hasn't changed.

I used the same pattern for JsonbConfigCustomizer.

@Ladicek finally found a reference than instances in Instance would be sorted but given it's very clear in the @All contract, it doesn't hurt to use this one instead.
