2ee5c58401359a85229fcfddff212a8d86932f12  [Site Isolation] Remove usage of `convertRectToMainFrameCoordinates` in `WebPageProxy::showDataListSuggestions`

not a security fix confidence 0.12 signal score 6.2 Source/WebCore/html
Classified as not security-relevant.
Triage note: Renames elementRectInRootViewCoordinates to ...MainFrameView..., removes the async convertRectToMainFrameCoordinates hop in showDataListSuggestions, and caches/resets m_frameGeometry/m_frameViewportInfo on didCommitLoad. Coordinate-space/plumbing refactor for site isolation.
This commit was flagged by the signal scorer and reviewed by AI (not a human). It is listed only so the triage is auditable; there is no root-cause analysis because this is not a vulnerability fix.
