Optimize module for "ConstrainedLanguage"

[hahazeMSFT]

Currently can't import module in ConstrainedLanguage mode.

PS C:\WINDOWS\system32> $ExecutionContext.SessionState.LanguageMode = "ConstrainedLanguage"
PS C:\WINDOWS\system32> Import-Module MSAL.PS -Verbose

I think there are several reasons the module will not work in ConstrainedLanguage mode at the moment. I'll keep this open as something to investigate but it would like require significant rework, if it is even possible.
