add decoding for CL_SEMAPHORE_EXPORT_HANDLE_TYPES

[bashbaug]

Observed Behavior

There is currently no behavior for decoding CL_SEMAPHORE_EXPORT_HANDLE_TYPES when creating a semaphore for export.

Desired Behavior

Best case: decode the handle types for CL_SEMAPHORE_EXPORT_HANDLE_TYPES. At minimum, properly skip this property, since it is a list of variable length.

Steps to Reproduce

Create a semaphore with the CL_SEMAPHORE_EXPORT_HANDLE_TYPES property with CallLogging enabled.
