currently we multiplied the requesting size when adding to loading, but
did not do so when estimating projected usage.

The root cause of the issue lies in the fact that when a sealed segment
contains multiple row groups, the get_cells function may receive
unordered cids. This can result in row groups being written into
incorrect cells during data retrieval.
Previously, this issue was hard to reproduce because the old Storage V2
writer had a bug that caused it to write row groups larger than 1MB.
These large row groups could lead to uncontrolled memory usage and
eventually an OOM (Out of Memory) error. Additionally, compaction
typically produced a single large row group, which avoided the incorrect
cell-filling issue during query execution.

This patch makes `PackedReader` return EOF when try to calling
`ReadNext` after closing it.
This behavior make importv2.binlog reader could retry after EOF reached

When `MultiSaveAndRemove` like ops contains same key in saves and
removal keys it may cause data lost if the execution order is save first
than removal.
This PR make all the kv execute removal first then save the new values.
Even when same key appeared in both saves and removals, the new value
shall stay.

Previous code uses diskSegmentMaxSize if and only if all of the
collection's vector fields are indexed with DiskANN index.
When introducing sparse vectors, since sparse vector cannot be indexed
with DiskANN index, collections with both dense and sparse vectors will
use maxSize instead.
This PR changes the requirments of using diskSegmentMaxSize to all dense
vectors are indexed with DiskANN indexs, ignoring sparse vector fields.

This patch fixes following logic bug:
- When multiple chunks are loaded and size cannot be divided by 8, just
appending uint8_t as bitmap will cause null bitmap dislocation
- `null_bitmap_data()` points to start of whole row group, which may not
stand for current `arrow::Array`
The current solutions is:
- Reorganize the null_bitmap with currect size & offset
- Pass `array->offset()` in tuple to info the current offset
