issue: #43261
`promise->setValue(folly::Unit());` may run callbacks inline and some of
them may attempt to grab `mtx_`. So we should not call
`promise->setValue(folly::Unit());` while holding the lock.

This PR also:
1. removed ERROR state from ListNode
2. CacheSlot will do reserveMemory once for all requested cells after
updating the state to LOADING, so now we transit a cell to LOADING
before its resource reservation
3. reject resource reservation directly if size >= max_size

this PR also makes HasRawData of ChunkedSegmentSealedImpl to return
based on metadata, without needing to load the cache just to answer this
simple question.

storage v2 chunked seal segment loading is based on caching layer. A
cell unit in storage v2 is a parquet row group in remote object storage,
containing all fields. Therefore, each field needs a proxy to do related
one field operations.
