Paste text thru keyboard input (or emulated keypresses)

Is your feature request related to a problem? Please describe. Often using VMs where clipboard is not available and need to input text, sometimes just a product key or other "simple" text.

Describe the solution you'd like Make it possible to "paste" text and have it be sent as keystrokes. Also mentioned in https://github.com/TigerVNC/tigervnc/issues/2066#issuecomment-5159754006

Describe alternatives you've considered Using other clients where this feature exists or is simple to add, but TigerVNC is my recommended and approved client.

Additional context I know that scancodes will become messy here with different layouts etc, but I still think it is worth it. As mentioned in the linked comment above an OSD keyboard that covers all the "send keypress" scenarios is a good alternative, and in such UI the "send text as keystrokes" would be an even better place and UX.
