feat: Builtin settings objects from Setup section of Fluent's outline tree

[mkundu1]

The classes for built-in settings objects from the Setup section of Fluent's outline tree are generated in a codegen step. Following is an example script using those classes. I'll add the settings classes from the Solution and Results sections of Fluent's outline tree.

Example script:

import ansys.fluent.core as pyfluent
from ansys.fluent.core import Viscous, VelocityInlet, BoundaryConditions
solver = pyfluent.launch_fluent()
solver.file.read_case(file_name=r"d:\work\elbow.cas.h5")
visc = Viscous(solver=solver)
cold_inlet = VelocityInlet(solver=solver, name="inlet2")
bc_group = BoundaryConditions(solver=solver)
