0569e731 - Improve presentation in Google sheets (with Braille mode enabled) (#7935)

Improve presentation in Google sheets (with Braille mode enabled) (#7935) * Improve presentation in Google Sheets (in braille mode). * An IAccessible NVDAObject with both a readonly state and editable state should remove its editable state and class itself as just readonly. This ensures that table cells with the readonly state within a contenteditable (such as Google sheets) are correctly presented and do not announce as editable text. * Report friendly cell coordinates for spreadsheets in Firefox and Chrome similar to MS Excel, by exposing coltext and rowtext IAccessible2 attributes via the cellCoordsText property. * IAccessible NVDAObject's positionInfo property: don't expose indexInGroup or similarItemInGroup if this object supports the IAccessibleTableCell interface as a cell's 2d info is much better position information.
