Support manually adding a binary view into the debugger binary view

[xusheng6]

Right now the debugger dynamically checks the list of loaded modules, and whenever the input file is seen in the list, the binary view for that module is rebased and then added into the debugger binary view. However, this is not enough in several cases:

1. The user wishes to add multiple binary views into the debugger binary view, e.g., a .exe and a DLL
2. The user initially does not specify the input module, and later wishes to add a view into the debugger binary view

Note, we should also allow the user to configure whether the option should be repeated when the target is restarted.
