Summary of the new feature / enhancement

The $ErrorView variable was introduced earlier than $PSStyle. But with $PSStyle containing configuration like $PSStyle.Formatting and $PSStyle.Progress, it feels to me the error view configuration should be moved to $PSStyle as well, for consistency and easier discoverability.

Proposed technical implementation details (optional)

Discard the $ErrorView variable (breaking change), add the public property ErrorView to System.Management.Automation.PSStyle.
