Fix multiple consistency bugs

[zhenchaoni]

Fixes #565, #510

For #565 ,
For all command, use the shared device_op[tion and ep_option util. Therefore, all commands can have consistent CLI option name.

For #510 ,
Some URL in our project is still referencing the old wording "modelkit". Now change them to "winml"

https://github.com/microsoft/winml-cli/pull/816/changes

@xieofxie The changes are basically the same. To avoid conflict, I will remove those duplicate changes in my PR. Then, this PR will not overlap with the other 2.
