Allow user to customize variable presentation when debugging through Visual Studio

[AdamYoblick]

Same as the vscode request at microsoft/vscode-python-debugger#165

Describe the feature you are requesting
I want to be able to customize how variables are presented in the visual studio debugger (hide built-in functions, for example).

Reasons for requesting this feature
Less noise, makes debugging more efficient. This is also requested by vscode users, as well as a dev community ticket for PTVS.

Describe alternatives you've considered
There are no alternatives, there's no way to hide the extra stuff.

Additional context
Here's a screenshot of a repro:

Remaining tasks:

• Proof of concept
• Create variable presentation options at Tools -> Options -> Python -> Debugging
• Remove hardcoded POC values and hook up to options page
• Coordinate with VS UI team to get options page UI approval?
• Coordinate with vscode team to synchronize releases?

Proof of concept is complete. 😄
