[PropertyGrid] FolderNameEditor does not use the modern FolderBrowserDialog

### Background and motivation

The FolderBrowserDialog was extended to show the modern Vista folder browser dialog by default (when `AutoUpgradeEnabled` is true). However, the FolderNameEditor used for folder paths in a PropertyGrid was not updated to support this and always uses the old folder browser dialog.

### API Proposal

No API additions are needed, but an equivalent AutoUpgradeEnabled property could be added to FolderNameEditor if needed.

### API Usage

### Alternative Designs

### Risks

### Will this feature affect UI controls?

Properties using the FolderNameEditor will show the modern FolderBrowserDialog by default when opening the editor instead of the old one.
