### Purpose
<!-- Linking this pull request to the issue -->
Linked issue: close #3613
<!-- What is the purpose of the change -->
Add `tabletServer` resource reporting and a coordinator-side
`KvLeaderReplicaCapacityManager` to protect clusters from creating too many KV
leader replicas.
`TabletServers` now report optional CPU and memory information during
registration. The coordinator derives `kvLeaderReplicaCapacity` from live
`tabletServer` memory and `kv.leader-replica.memory-reserved`, tracks the
current KV leader replica count in memory, rebuilds it on coordinator
leadership startup, and checks/reserves capacity when creating KV tables or
partitions.
The capacity limit is disabled unless more than half of live tablet servers
report memory. Unknown-memory `TabletServers`use the average known memory when
the limit is enabled.
Also add dynamic config support, metrics, RPC error mapping, serde
compatibility, auto-partition accounting, and tests for resource probing,
capacity calculation, manual create/drop, and auto partition create/drop.
