Description
Is your feature request related to a problem? Please describe.
When calling a native application, such as powershell.exe, carriage return \r is retained, causing problem down the pipeline.
$ result=$(powershell.exe "Write-Output test")
$ python3 -c "import sys; print(sys.argv)" "$result"
['-c', 'test\r']
The actual output of powershell.exe contains \r\n, but WSL only removes \n, leaving \r in the output.
Describe the solution you'd like
WSL should be smart enough to remove \r.
Additional context
This causes failure when calling Azure CLI installed on Windows (C:\Program Files (x86)\Microsoft SDKs\Azure\CLI2\wbin\az.cmd) from WSL (https://github.com/Azure/azure-cli/issues/13573#issuecomment-888791313).

Research direction
Start by reproducing the powershell.exe command from the issue and inspect where WSL handles native application output and strips line endings. Done means carriage returns from CRLF output are removed in command substitution while the existing newline behavior remains correct; the issue does not name a source file or test.
