Some legacy code in PowerShell checks the current Windows process architecture and if it is ARM forces PowerShell to run in Constrained Language mode.

https://github.com/PowerShell/PowerShell/blob/master/src/System.Management.Automation/security/wldpNativeMethods.cs#L341

This is not needed anymore and ARM platforms should run PowerShell in FullLanguage mode by default.

Steps to reproduce

$ExecutionContext.SessionState.LanguageMode

Expected behavior

FullLanguage

Actual behavior

ConstrainedLanguage
