8dbdbd3b - [mlir] Support thread-safe context access without parallel execution (#236551)

[mlir] Support thread-safe context access without parallel execution (#236551) Add enableThreadSafeLocking() and isThreadSafeLockingEnabled() so clients using external threads can unique context-owned entities without enabling MLIR parallel execution or creating a thread pool. Use the locking mode for operation-name uniquing as well as the type, attribute, and affine uniquers. Enabling multithreading also enables locking. Follow-up to #235294. Assisted-by: Codex
