Remove FieldContext hotkey scope as:
- each Field should set its own hotkey scope (ex:
emails-field-input-{recordId} or emails-field-input for now)
- while opening a fieldInput, we should synchronously set the
corresponding hotkey scope
To cut this refactoring in half, I'm allowing all input to use
TableHotkeyScope.CellEditMode
