[w3c/clipboard-apis] Data store's mode should be readonly when firing a pate event (#45)

[fire a clipboard event](https://w3c.github.io/clipboard-apis/#fire-a-clipboard-event) step 7.1.1. says:
> Set the clipboard-event-data’s internal drag data store mode flag to read/write.

but it should be read-only instead since the script has no business writing into clipboard as the user intends to paste contents into the page from the pasteboard/clipboard.
