Add pb.Provider.ToProviderInfo test helper method

[VenelinMartinov]

This PR adds a ToProviderInfo test helper method to the providerbuilder test class. providerbuilder is the blessed way to build PF providers and we have various repeated code for turning this into a bridged provider ProviderInfo. The new method aims to consolidate them. This should also help with discoverability.

This is good. I think it would be easier to review if it was combined with #2812, since we could see both the new method and it's usage.
