Improve view in Solution PM UI for Solution Explorer gold bar entry point

[jebriede]

Bug

Fixes: NuGet/Home#13050

Description

Open the Solution PM UI to the Installed tab with the Show Only Vulnerable packages filter checked when entering the PM UI from the gold bar in the Solution Explorer that warns of vulnerable packages in the solution.

To accomplish this, added launch options to the existing Solution PM UI command handler that supports opening the PM UI to a specific tab and with specific filters on, off, or with default values.

PR Checklist

• Meaningful title, helpful description and a linked NuGet/Home issue
• Added tests
• Link to an issue or pull request to update docs if this PR changes settings, environment variables, new feature, etc.

Manual validation of scenario:
Clicking the Manage NuGet Package link in the Solution Explorer will take you to this view:

I verified that this view opens even when the Solution PM UI had not previously been opened and thus the extension hadn't been preloaded.

If the Solution PM UI is already open, clicking this link will switch to the Installed tab with the Show only vulnerable packages option checked.

Also, regression tested the menu item by right clicking the Solution -> Manage NuGet Packages for Solution... as well as Tools -> NuGet Package Manager -> Manage NuGet Packages for Solution...

Code looks good. Would be nice to have a screenshot and to describe the validation a bit as well.

@donnie-msft thanks! I've refactored the PR quite a bit and, in this iteration, I've added more details about the validation and a screenshot thanks to your suggestion.
