This PR introduces as sharded mutex within the ChainIndex#GetTipsetByHeight.
It also replaces a go map with xsync.Map which doesn't require locking.
The lock is taken when it appears that ChainIndex filling work should be
started. After claiming the lock, the status of the cache is rechecked,
if the entry is still missing, the fillCache is started.
Thanks to @snissn and @arajasek for debugging and taking initial stabs at this.
Supersedes #10866 and 10885

* Fix 1.21 regression: GET_32G_MAX_CONCURRENT + mixed prepared/executing leads to stuck scheduler
If you have 12 GET tasks and GET_32G_MAX_CONCURRENT=1, sealing jobs will only show assigned tasks for GET of the miner
and is stuck.
I believe this to be a regression of 1.21 unifying the counters, in the case of GETs where PrepType and TaskType
both being seal/v0/fetch leading to a state where tasks are blocked since already counted towards the limit.
* itests: Repro issue from PR #10633
* make counters int (non-working)
* fix: worker sched: Send taskDone notifs after tasks are done
* itests: Make TestPledgeMaxConcurrentGet actually reproduce the issue
* make the linter happy

* release the read lock earlier as it is not needed for chaincomputebasefee
* chain/messagepool/selection.go change to read lock in SelectMessages
* tighten up locks in chain/messagepool/repub.go and two questions on whether curTsLks are needed as comments
* include suggestion from @Jorropo to preallocate our msgs array so that we only need to make a single allocation
* mp.pending should not be accessed directly but through the getter
* from @arajasek: just check whether the sender is a robust address (anything except an ID address is robust) here, and return if so. That will:
be faster
reduce the size of this cache by half, because we can drop mp.keyCache.Add(ka, ka) on line 491.
* do not need curTslk and clean up code comments
* Make lotus-worker report GPU usage to miner during ReplicaUpdate task
* make gen
