Unbundle metrics with 2 labels

[dapplion]

CPU profiles show that the cost of handling metrics with 2 labels is relatively high for hot paths like once per message. The two current offenders could be unrolled into multiple metrics with a single label:

Biggest offender

js-libp2p-gossipsub/src/metrics.ts

Lines 341 to 345 in f62859b

	msgReceivedStatus: register.gauge<{ topic: TopicLabel; status: MessageStatus }>({
	name: 'gossipsub_msg_received_status_total',
	help: 'Tracks distribution of recv msgs by duplicate, invalid, valid',
	labelNames: ['topic', 'status']
	}),

Rest of good targets to unbundle

js-libp2p-gossipsub/src/metrics.ts

Lines 303 to 307 in f62859b

	msgPublishPeersByGroup: register.gauge<{ topic: TopicLabel; peerGroup: keyof ToSendGroupCount }>({
	name: 'gossipsub_msg_publish_peers_by_group',
	help: 'Total count of peers (by group) that we publish a msg to',
	labelNames: ['topic', 'peerGroup']
	}),

js-libp2p-gossipsub/src/metrics.ts

Lines 237 to 241 in f62859b

	asyncValidationResult: register.gauge<{ topic: TopicLabel; acceptance: TopicValidatorResult }>({
	name: 'gossipsub_async_validation_result_total',
	help: 'Message validation result for each topic',
	labelNames: ['topic', 'acceptance']
	}),
