[ios] Creates ToolsMenuModel Class
Extracts the Model related code from ToolsMenuViewController to a new
class named ToolsMenuModel.

This CL is just the first step on refactoring and decoupling the Model
logic, so it can be used by the new ToolsMenuVC and the old one.

Hi Mark, Rohit,

An internal test was failing so I had to revert the original CL. I've now fixed
that and also created a downstream CL to fix the test. Could you PTAL.

Thanks

Please disregard this CL, I'll create 2 upstream CL's so I don't break the
auto-roller.

Please close this CL in that case.
