Update ui/src/components/popovers/PasteModal.tsx

Suspend KeyDownMessages while processing a macro.
Make sure we don't emit huge debugging traces.
Allow 30 seconds for RPC to finish (not ideal)
Reduced default delay between keys (and allow as low as 0)
Move the HID keyboard descriptor LED state
as it seems to interfere with boot mode
Run paste/macros in background on their own queue and return a token for cancellation.
Fixed error in length check for macro key state.
Removed redundant clear operation.
Use Once instead of init()
Add a time limit for each message type/queue.

+### "Device UI Fails to Build"
+
+If while trying to build you run into an error message similar to :
+```plaintext
+In file included from /workspaces/kvm/internal/native/cgo/ctrl.c:15:
+/workspaces/kvm/internal/native/cgo/ui_index.h:4:10: fatal error: ui/ui.h: No such file or directory
+ #include "ui/ui.h"
+          ^~~~~~~~~
+compilation terminated.
+```
+This means that your system didn't create the directory-link to from _./internal/native/cgo/ui_ to ./internal/native/eez/src/ui when the repository was checked out. You can verify this is the case if _./internal/native/cgo/ui_ appears as a plain text file with only the textual contents:
+```plaintext
+../eez/src/ui
+```
+
+If this happens to you need to [enable git creation of symbolic links](https://stackoverflow.com/a/59761201/2076) either globally or for the KVM repository:
+```bash
+   # Globally enable git to create symlinks
+   git config --global core.symlinks true
+   git restore internal/native/cgo/ui
+```
+```bash
+   # Enable git to create symlinks only in this project
+   git config core.symlinks true
+   git restore internal/native/cgo/ui
+```
+
+Or if you want to manually create the symlink use:
+```bash
+   # linux
+   cd internal/native/cgo
+   rm ui
+   ln -s ../eez/src/ui ui
+```
+```dos
+   rem Windows
+   cd internal/native/cgo
+   del ui
+   mklink /d ui ..\eez\src\ui
+```
