feat: Builtin settings classes for Solution section

[mkundu1]

The following changes are included in this PR:

1. Support of the following APIs for named objects:

ReportFile(solver=solver, name="report-file-1")  # returns existing object
ReportFile(solver=solver, new_instance_name="report-file-1")  # creates new object with name=<new_instance_name>
ReportFile(solver=solver)  # Creates new object with automatic naming

2. Cover settings classes for Solution section of Fluent's outline view.

Future changes:

1. Ability to attach/re-attach session attribute with the class instance.
2. Better exception type/message.
3. Cover the remaining sections of Fluent's outline view.
