Re-enable support for deterministic pack

Make NuGet pack more determinisitic, by default.

This makes `Deterministic` property (default = `true`) work again for
nuget pack via msbuild.

It adds support for `DeterministicTimestamp` property (default = `true`)
too.

For more details about the properties and the design goals, see:

- NuGet/Home#14785
- https://github.com/NuGet/Home/main/accepted/2026/deterministic-pack-revisited.md

Fixes: NuGet/Home#8601
