Restrict Windows IDE pipe client impersonation ( #39020 )
...
## Why
Windows named pipe servers can impersonate connected clients. IDE context
connections only require the server to identify the client, so they should not
grant broader impersonation rights.
## What changed
Open Windows IDE context pipes with `SECURITY_SQOS_PRESENT` and
`SECURITY_IDENTIFICATION`, limiting the server's impersonation token to the
identification level.
## Testing
Add a Windows regression test that connects to a named pipe, asks the server to
impersonate the client, and verifies that the resulting token has the
`SecurityIdentification` level.
