provide setters for the various SQL queries used in the JDBC persistence types

[joshlong]

some of the queries that are only available as private final fields in the classes are incompatible with certain databases, like Oracle.

for example JdbcChatMemory uses a query with limit which wont work on Oracle.

There's no easy way to fix this short of copy-and-pasting the entire class and excluding Spring AI's solution. if you provide a few setters or make the queries constructor arguments, that would be sufficient to unblock

please do this for anything that uses JDBC

This has been address, the refactoring to focus on JdbcChatMemoryRepository and there isn't an impl of JdbcChatMemory anymore. PR #3037 shows how we support multiple dialects.
