[Site Isolation] [macOS] DOM paste access fails to actually allow pasteboard
access in cross-origin subframes
https://bugs.webkit.org/show_bug.cgi?id=319290
rdar://182129589
Reviewed by Abrar Rahman Protyasha.
On macOS only, we failed to pass the frame ID where pasteboard access was
requested when calling
into `grantAccessToCurrentPasteboardData`; this causes pastes to fail with
`NotAllowedError`, even
after the user selects 'Paste' in the programmatic paste menu.
Fix this by taking `requestFrame` from the `m_domPasteState`, and passing it in.
