Admin UI: include ec shard sizes into volume server info (#7071)

* show ec shards on dashboard, show max in its own column

* master collect shard size info

* master send shard size via VolumeList

* change to more efficient shard sizes slice

* include ec shard sizes into volume server info

* Eliminated Redundant gRPC Calls

* much more efficient

* Efficient Counting: bits.OnesCount32() uses CPU-optimized instructions to count set bits in O(1)

* avoid extra volume list call

* simplify

* preserve existing shard sizes

* avoid hard coded value

* Update weed/storage/erasure_coding/ec_volume_info.go
