[Improvement] Possible threading issue in BaseCatalog.java, BasePropertiesMetadata.java, BaseTable.java and sqlSessionFactory.java

### What would you like to be improved?

The fields ops, capability, and properties are marked as volatile. However, doing this is not enough to make the code thread safe as those types are not thread-safe.

The same issue exists for propertyEntries in BasePropertiesMetadata.java, ops in BaseTable.java and sqlSessionFactory in sqlSessionFactory.java.

### How should we improve?

Make the code thread safe.

Start by reading BaseCatalog.java, BasePropertiesMetadata.java, BaseTable.java, and sqlSessionFactory.java, focusing on the volatile fields ops, capability, properties, propertyEntries, and sqlSessionFactory and how they are accessed. Trace their mutable types and concurrent call paths before deciding what thread-safety guarantees are required. Done means these accesses are safe under concurrent use, with tests covering the identified races.
