Create a custom ContextMenuItem object to insert into the WebView context menu.
CoreWebView2 will rewind the icon stream before decoding.
There is a limit of 1000 active custom context menu items at a given time.
Attempting to create more before deleting existing ones will fail with
ERROR_NOT_ENOUGH_QUOTA.
It is recommended to reuse ContextMenuItems across ContextMenuRequested events
for performance.
The returned ContextMenuItem object's IsEnabled property will default to TRUE
and IsChecked property will default to FALSE. A CommandId will be assigned
to the ContextMenuItem object that's unique across active custom context menu items,
but command ID values of deleted ContextMenuItems can be reassigned.
