MdeModulePkg UsbBotPei: The UsbBotPei module contains the private structure definition used by the UsbBusPei module.
If the structure layout in UsbBusPei is changed, then the UsbBotPei will not work.
1. As the maximum number of endpoints is 16, use UINT16 type rather than UINT8 for DataToggle.
2. DataToggle needs to be reset to 0 when endpoint stall is cleared, do it in PeiUsbControlTransfer().
