• Make ShellExecuteEx run in a STA thread. (#4362)

General cmdlet updates and fixes

Installer updates

• Create script to install latest PowerShell from Microsoft package repositories (or Homebrew) on non-Windows platforms. (#3608) (Thanks to @DarwinJS!)
• Enable MSI upgrades rather than a side-by-side install. (#4259)
• Add a checkbox to open PowerShell after the Windows MSI installer has finished. (#4203) (Thanks to @bergmeister!)

• Disable legacy UTC and SQM Windows telemetry by enclosing the code in '#if LEGACYTELEMETRY'. (#4190)

Cleanup #if CORECLR code

PowerShell 6.0 will be exclusively built on top of CoreCLR,
so we are removing a large amount of code that's built only for FullCLR.
