Consider adding option to include resource private state in JSON output

[gdavison]

Terraform Version

Terraform v1.9.8
on darwin_arm64

Use Cases

This is requested primarily to support provider plugin testing: hashicorp/terraform-plugin-testing#321. There isn't currently a way to validate what private state values are set, and terraform-plugin-testing relies on the JSON output

Attempted Solutions

None

Proposal

Add an option to include private values in Terraform JSON output. Since it's not something that generally should be used, use a command line flag to enable it.
