Description

Added type checks in setter methods of different browser options.

Motivation and Context

The type check was not being done before setting the values of some browser options (e.g binary_location) in setter methods of different browsers. I have added these validations in setter methods of below options.

• chromium/options.py
• firefox/options.py
• safari/options.py
• wpewebkit/options.py
• safari/services.py
