Get the tasks in workflow order in meshing workflows

[mkundu1]

From @rploconnor:

There should be a way to get the tasks in the workflow order in meshing workflows as presented in the Fluent GUI. Currently, the tasks are returned in the following order.

>>> import ansys.fluent.core as pyfluent
>>> meshing = pyfluent.launch_fluent(mode="meshing")
>>> wt = meshing.watertight()
>>> wt.tasks()
[<Task 'Generate the Volume Mesh'>, <Task 'Generate the Surface Mesh'>, <Task 'Add Boundary Layers'>, <Task 'Create Regions'>, <Task 'Add Local Sizing'>, <Task 'Update Regions'>, <Task 'Update Boundaries'>, <Task 'Import Geometry'>, <Task 'Enclose Fluid Regions (Capping)'>, <Task 'Apply Share Topology'>, <Task 'Describe Geometry'>]
