Add DatabaseClient bind variant for list of parameters

Prior to this commit, the `DatabaseClient` interface would allow batch
operations for binding parameters by their names and values. Positional
parameters did not have such equivalent.

This commit adds a new `bindValues(List<?>)` method variant for adding
multiple positional arguments in a single call and avoiding allocation
overhead when the parameters count is large.

Closes gh-33274
