Don't ignore ConsoleKey.Packet type as that is simply Unicode

[SteveL-MSFT]

PR Summary

When using IOS Remote Desktop client, the virtual keyboard sends keypresses as ConsoleKey.Packet which per documentation is used to pass Unicode characters, so we should not be ignoring those. The previous code ignored this, so those characters were dropped. Tested manually.

Fix #1428

Just to add more context information about the ConsoleKey.Packet: https://stackoverflow.com/a/66918568.

Used to pass Unicode characters as if they were keystrokes. The VK_PACKET key is the low word of a 32-bit Virtual Key value used for non-keyboard input methods.

INPUT_KEYBOARD supports nonkeyboard-input methods—such as handwriting recognition or voice recognition—as if it were text input by using the KEYEVENTF_UNICODE flag. If KEYEVENTF_UNICODE is specified, SendInput sends a WM_KEYDOWN or WM_KEYUP message to the foreground thread's message queue with wParam equal to VK_PACKET.
