[data grid] Make value and colDef accessible in actions column

[aress31]

Summary

The params in getActions are only row, id and and columns; there is no information about the currently processed column or value which is quite restrictive when using type mappings. Addin them would improve DX and remove boilerplate code.

Examples

const getTypeMappings = (field) => ({
  // --- SNIP ---
  bytea: {
    headerName: undefined,
    type: "actions",
    getActions: ({ row }) => {
      const dataUrl = hexStringToDataUrl(row[field]);
      return [
        <GridActionsCellItem
          onClick={() => downloadFile(dataUrl)}
          icon={<Download />}
          label="Download"
          disabled={!dataUrl}
        />,
      ];
    },
  },
  // --- SNIP ---
});

Note: Also, transformations within valueGetter don't seem accessible to getActions too.

Motivation

Improve the DX and provide contextual info to getActions.

Hey @aress31 ... why would you need a value or valueGetter in getActions? The actions col is a special column which purpose is simply to render a series of buttons that perform actions on the row in question. That's exactly why we pass the row as a property to it.

Could you explain your specific use case please?

@michelengelen simply because my action column need contextual information such as the current value/column name to process the action logic. See the code snippet in my opening message.
