Prior to this commit, `DataSourceJmxConfiguration` with tomcat `DataSource`, it can only find `DataSourceProxy` if the given `DataSource` is a direct child of it. Since it uses `instanceof`, it could not find `DataSourceProxy` if the `DataSource` is wrapped(delegated) or proxied. This is because `DataSourceProxy#unwrap()` always returns null; thus cannot use this method to directly obtain `DataSourceProxy`. In this commit, updated the check logic to perform the best effort to retrieve `DataSourceProxy`. If given `DataSource` is wrapped or proxied by spring, tries to unwrap or get target datasource recursively to find `DataSourceProxy`.

DataSourceJmxConfigurationwith tomcatDataSource, it can only findDataSourceProxyif givenDataSourceis a direct child of it.The check logic uses
instanceof. When targetDataSourceis wrapped(delegated) or proxied, it cannot findDataSourceProxy.Since
DataSourceProxy#unwrap()always returns null, here cannot use this method to directly obtainDataSourceProxy.In this PR, updated the check logic to perform the best effort to retrieve
DataSourceProxy. If givenDataSourceis wrapped or proxied by spring, tries to unwrap or get target datasource recursively.
