Description

This PR updates NuGet signed package verification on Linux and macOS to use 2 separate fallback certificate bundles instead of 1.

Prior to this change, NuGet would use a single fallback certificate bundle which contained root certificates valid for both code signing and timestamping. Roots valid for only code signing or only timestamping were not in the certificate bundle because a consumer had no way of knowing which certificates were valid for which purpose(s).

Whatever trust anchors we use must be valid for CS and TS. Actually, it's a bit more nuanced in that whatever set of trust anchors we use for purpose X must be valid for purpose X. The set of trust anchors valid for CS and the set of trust anchors valid for TS intersect but do not necessarily overlap. Using a trust anchor that is only valid for TS (or TLS, for that matter) to verify a CS certificate would be incorrect.

Customer Impact

Not having separate CTLs fails the verification of a set of packages on nuget.org. The expectation is that all packages form NuGet.org pass validation. This change allows verification to enabled as opt-in and have confidence that it'll work.
