Introduces an ABI change to the ConptyClearPseudoConsole signal. Otherwise, we have to make it so that the API call always retains the row the cursor is on, but I feel like that makes it worse. Closes #18732 Closes #18878 ## Validation Steps Performed * Launch `ConsoleMonitor.exe` * Create some text above & below the cursor in PowerShell * Clear Buffer * Buffer is cleared except for the cursor row ✅ * ...same in ConPTY ✅
