RMW implementation (if applicable):

RMW Configuration (if applicable):

When using PCL for point clouds, one can easily add uint64 fields to the point cloud.
Conversion messages work as expected, and ROS messages are sent.
Same for int64 and bool.

However, the value of the datatype field is not yet available in the PointField message definition.
As a result, some Python libraries fail when trying to convert the message back to a point cloud.

Client library (if applicable):

No response

'ros2 doctor --report' output

Steps to reproduce issue

1. Create a point cloud definition that includes either of: int64, uint64, or bool
2. Send PointCloud2 message via ROS
3. inspect message, e.g., with cli tools

Expected behavior

I would expect that every number that the datatype field may have is available in the PointField message definition.

Actual behavior

Missing entries for the following data types:
-> datatype: 9 (for int64)
-> datatype: 10 (for uint64)
-> datatype: 11 (for bool)
