[Shell] Azure CLI receives corrupted arguments in PowerShell

[jiasli]

Describe the bug

When invoking az in PowerShell, due to the known issue of PowerShell https://github.com/PowerShell/PowerShell/issues/1995, arguments passed to Azure CLI may get corrupted. For example, literal double quotes (") are lost:

# PowerShell
> az '{"signInAudience":"AzureADAndMicrosoftAccounts"}' --debug
Command arguments: ['{signInAudience:AzureADAndMicrosoftAccounts}', '--debug']

This contradicts the behavior of Bash:

# Bash
$ az '{"signInAudience":"AzureADAndMicrosoftAccounts"}' --debug
Command arguments: ['{"signInAudience":"AzureADAndMicrosoftAccounts"}', '--debug']

Impact

This is mainly affecting

• passing JSON as an argument as in az rest --body {JSON} (#15512)

  # not working
  az rest ... --body '{"signInAudience":"AzureADandPersonalMicrosoftAccount"}'
  # working
  az rest ... --body '{\"signInAudience\":\"AzureADandPersonalMicrosoftAccount\"}'
  

• using JMESPATH --query (#13152)

  # not working
  az version --query '"azure-cli"'
  # working
  az version --query '\"azure-cli\"'
  

Workaround

Until this issue is fixed by PowerShell, arguments with special characters (", ,, &...) need to be escaped twice, one for CMD, one for PowerShell.
