The fields and partitions information are stored and fetched with
different prefixes in the metadata. In the CreateCollectionTask, the
RootCoord checks the existing collection information against the
metadata. This check fails if the order of the fields or partitions info
differs, leading to an error after restarting Milvus. To resolve this,
we should use a map in the check logic to ensure consistency.

Add a new utitliy function in `pkg/util/typetuil` to pre-allocate field
data slice capacity acoording to search limit. This shall avoid copying
the data during `AppendFieldData` when previous slice is out of space.
And shall also save CPU time during high paylog.
