Make license of binaries more clear

Issue Title

Make license of binaries more clear

General

For binary files list on the official download page: https://dotnet.microsoft.com/download/dotnet-core/2.1
Its not clear what the license is for each download. Since these are a combination of multiple repositories its not easy to deduce what the actually license is for each file / Operating system.
In https://github.com/dotnet/coreclr/blob/master/Documentation/project-docs/copyright.md it states

.NET Core distributions are licensed with a variety of licenses, dependent on the content. By default, the MIT license is used, the exact same as the source license, with the same copyright holder. There are some cases where that isn't possible because a given component includes a proprietary Microsoft binary. This is typically only the case for Windows distributions.

but doesn't really give any concrete links to which files have which licenses.

Would it be possible to update the download page https://dotnet.microsoft.com/download/dotnet-core/2.1 and indicate the license for each of the files?

As of right now, the only indication of the license is the generic "Terms of Use" link at the bottom of the page:
https://www.microsoft.com/en-us/legal/intellectualproperty/copyright/default.aspx which basically contradicts the opensource licenses

AFAIK, the download archives (at least the tar.gz versions) themselves include LICENSE and possibly THIRD-PARTY-NOTICE files to clarify the license of that download. The license is (or was, at least) different for different downloads.

This advice from Omair continue to be very good: #2955 (comment).

I also added this file to help. https://github.com/dotnet/core/blob/main/license-information-windows.md.

Closing this issue, since I believe this is a satisfactory answer.
