Replaces DataContractSerialization with XElement.ToString()

Fixes an oversight bug I found, where I was throwing from properties that were used in databinding.

Use web storage for test caching layer

The Jenkins build is copying Newtonsoft.Json into the output directory.  This is not happening locally and the version chosen by Jenkins is not compatible with the one we are referencing here.  Moving to own output directory to eliminate this issue.

In preparation for moving to web storage.

Code Style: Analyzer/Fixer/Options for naming conventions 

Implements #7064

This change includes:

- An analyzer and codefix for enforcing naming styles and fixing symbol names to comply with a chosen & configurable set of naming rules.
- A set of Enforcement Levels that can be applied to different naming rules.
- A mechanism for linking from a lightbulb preview to the option that caused the related diagnostic to be created (could be moved to a different PR or release)
- Moving of the "Formatting" options pages under the Code Style node.

Consume new use var options from CodeGen features

This is part of #9155

Since, we replaced an existing user option about using var in local declarations with 3 new codestyle options, we need to update code generation features that were directly consuming these affected options.

This PR, selectively handles updating the consumers of the obsolete option and moving them over to use the new options.

The BooleanCodeStyleOptionViewModel are a glue between older checkbox
style options and the new grid UI with severity levels. Well, the older
options don't have severity levels and I was throwing NotSupportedEx,
but forgot they were used in databinding. As a result we had non-fatal
exceptions. This change removes them.
