guanchengang d571c4097d Lazily handle setClientInfo/setNetworkTimeout in LazyConnectionDataSourceProxy
This commit extends LazyConnectionInvocationHandler to cache early
calls to:

- setClientInfo(String, String)
- setNetworkTimeout(Executor, int)

These methods now defer physical connection acquisition until Statement
creation, consistent with existing lazy behavior for autoCommit,
readOnly, transactionIsolation, catalog, and schema.

We also accept and lazily cache calls to setNetworkTimeout() even when
the provided Executor is null. Since some JDBC driver implementations
completely ignore the Executor parameter (or fall back to a default
executor), we cannot meaningfully validate or handle a null Executor
before the physical connection is obtained.

getClientInfo() and getClientInfo(String) remain non-lazy (triggering
immediate connection fetch), because they are read operations whose
values cannot be reliably cached due to driver defaults, pooled
connection remnants, or external session modifications.

setClientInfo(Properties) also remains non-lazy. The reason is that JDBC
driver implementations are inconsistent. Some treat it as overwrite,
others as append/merge. To guarantee behavior identical to non-lazy
execution across all drivers, we choose not to cache or replay it,
avoiding any risk of semantic mismatch.

Closes gh-37261
