Roll forward (dotnet/core-setup#5691)

Roll forward (dotnet/core-setup#5691)

This is the new implementation of the framework resolution with the new roll forward setting.
The spec for this is [framework version resolution](https://github.com/dotnet/core-setup/blob/master/Documentation/design-docs/framework-version-resolution.md).

Major parts:
- introduce `rollForward` setting (CLI, env, config)
- convert the existing `rollForwardOnNoCandidateFx` to the new `rollForward` internally
- change framework reference compatibility algorithm to use the new `rollFoward` settings.
- basically rewrite the framework resolution algorithm with the new settings and fix an existing bug with incorrect retry logic
- add test infra for the new setting
- add tests for the new setting
