enhance: cache collection schema attributes to reduce proxy cpu (#29668)
See also #29113

The collection schema is crucial when performing search/query but some
of the information is calculated for every request.

This PR change schema field of cached collection info into a utility
`schemaInfo` type to store some stable result, say pk field,
partitionKeyEnabled, etc. And provided field name to id map for
search/query services.
