[bt][transport] Add inspectable send queue statistics

Wire PipelineMonitor to AclDataChannel by issuing tokens with each
ADC::SendPackets call that are retired upon their packets' exit
from the send queue.

Add "metrics" node to AclDataChannel inspect tree that contains the
quantile samples of send queue latency and payload sizes.

Bug: fxbug.dev/45725
Test: in bt-host-transport-tests,
ACLDataChannelTest.InspectHierarchyContainsOutboundQueueState
ACLDataChannelTest.SendingPacketsUpdatesSendMetrics

Pigweed

Pigweed is an open source collection of embedded-targeted libraries–or as we like to call them, modules. These modules are building blocks and infrastructure that enable faster and more reliable development on small-footprint MMU-less 32-bit microcontrollers like the STMicroelectronics STM32L452 or the Nordic nRF52832.

For more information please see our website: https://pigweed.dev/.
