Enhance 'install-powershell.ps1' to work on Linux/MacOS (#5411)
Enhance 'install-powershell.ps1' to work on Linux and macOS too. A user can install release version or daily powershell core on Linux and macOS. When `-AddToPath` is specified: - On Windows, add the absolute destination path to the 'User' scope environment variable 'Path'; - On Linux, make the symlink '/usr/bin/pwsh' points to "$Destination/pwsh"; - On MacOS, make the symlink '/usr/local/bin/pwsh' points to "$Destination/pwsh".
