dd-trace-js can't wrap `query` or `execute` method on mysql2@3.11.5

[0816i]

In version 3.11.5 of the mysql2 library (refer to the PR below), some dependencies have been reorganized, and the query, execute, and addCommand methods have been consolidated into the Connection class under the base directory.

Therefore, when creating hooks for the mysql2 library in datadog-instrumentations, it seems necessary to add hooks based on lib/base/connection.js for version 3.11.5.

Additionally, since the query and execute methods in lib/connection.js, lib/pool.js, and lib/pool_cluster.js also reference the query and execute methods in lib/base/connection.js, it is necessary to ensure that they are not hooked redundantly.
