[branch-2.1][fix](jdbc catalog) Fixed FE memory leak by enabling weak
references in HikariCP (#40923)
pick (#40773)
When FE collects statistics, its ThreadLocal will hold the ThreadLocal
of HikariCP in JdbcClient, making it difficult for HikariCP to be gc, so
this problem can be alleviated by enabling weak references of HikariCP.
