Add LICENSE/NOTICE.md to sqlcmd install folder

[stuartpa]

1. Add LICENSE/NOTICE.md to the install directory on Windows .msi installs (winget/choco)
2. Add arm/arm64 .msi builds (a separate winget repo PR adds these to the winget installer)
3. Also, align Architecture naming to winget/brew/debian:

So we will have:

x64 (for Windows/Mac)
amd64 (for Linux)

x86 (for Windows/Mac)
arm (for all Platforms)
arm64 (for all Platforms)

        "enum": [
          "neutral",
          "x64",
          "x86",
          "arm64",
          "arm"
        ],

This also seems to be align with brew:
