Nullable Quick Info for `field` uses unspeakable name

[RikkiGibson]

It looks like we only half-handled this for Quick Info.

@jasonmalinowski do you know which API is being used to display the symbol here? Maybe just Name? I am wondering if some SymbolDisplay needs to be used instead, or if IDE needs to special case it, or if compiler needs to expose something new for the layers to work appropriately..

Here's the code in question:

roslyn/src/Features/Core/Portable/QuickInfo/QuickInfoUtilities.cs

Lines 137 to 142 in 250126c

	var nullableMessage = flowState switch
	{
	NullableFlowState.MaybeNull => string.Format(FeaturesResources._0_may_be_null_here, symbol.Name),
	NullableFlowState.NotNull => string.Format(FeaturesResources._0_is_not_null_here, symbol.Name),
	_ => null
	};

I was thinking it might work to just display the field with a minimal format. What is the proper way to do this? Should I update implementation of ToDescriptionGroupsAsync so that it contains the stuff I need? Or just change the call to symbol.Name to some flavor of symbol.ToDisplayString()?

@CyrusNajmabadi for visibility

@RikkiGibson either are fine. we're not wedded to a particular approach.

Yep, ToDisplayString() is fine; I'd go with whatever you can pass to make it as short as possible, since otherwise it's redundant with what's above it.
