Resume-in-tab/drag-resume queued a cmd.exe-syntax command into a freshly
spawned tab whose live shell is the configured Windows shell (default
PowerShell). PowerShell mis-parsed the cmd ""-doubled wrapper and reported
"is not recognized as an internal or external command, operable program or
batch file", so the session never resumed.
Resolve terminalWindowsShell to a startup-shell family and quote the queued
command per shell (PowerShell Set-Location/$env, POSIX cd for git-bash),
only emitting the cmd /d /s /c wrapper when the live shell is cmd. The
copy-to-clipboard command is unchanged and stays cmd-wrapped.
Fixes#6152
