f418aa362c usbd_gs_can: clean up send to host path 
The USBD_GS_CAN_SendToHost() function is used to send to struct
gs_host_frame_object to the host.

Until this patch, after the sending process has been started, the
outgoing frame object is already added to the list of free objects and
the variable USBD_GS_CAN_HandleTypeDef::TxState is used to track if
the transfer to the host is in progress.

Instead, hold the outgoing object in
USBD_GS_CAN_HandleTypeDef::to_host_buf and move it to the free list
after the transfer is finished in USBD_GS_CAN_DataIn(). Use this to
track if a transfer is ongoing.

66f2f03d58 usbd_gs_can: USBD_GS_CAN_EP0_RxReady(): no need to copy hcan->ep0_buf to a locale variable 
In GS_USB_BREQ_IDENTIFY and GS_USB_BREQ_SET_TERMINATION the received
data is copied to a locale variable. Remove this and cast
hcan->ep0_buf to the struct gs_identify_mode respectively struct
gs_identify_mode.

Mark USBD_GS_CAN_HandleTypeDef::ep0_buf as aligned, so that it can be
casted to others structs that then can be dereferenced without
problems.

ea53735f4d usbd_gs_can: shrink CAN_CMD_PACKET_SIZE to minimal size 
Since commit "usbd_gs_can: USBD_GS_CAN_Config_Request(): pass data
buffer to USBD_CtlSendData() directly" control frames from Device ->
Host are not copied to hcan->ep0_buf anymore. Shrink
CAN_CMD_PACKET_SIZE to minimal size.

7d23053caa usbd_gs_can: USBD_GS_CAN_Config_Request(): pass data buffer to USBD_CtlSendData() directly 
Do not copy the control data to the intermediate buffer hcan->ep0_buf,
but directly pass the pointer to the data to USBD_CtlSendData().

Some data is located in the ROM (USBD_GS_CAN_btconst,
USBD_GS_CAN_dconf) while other is located in BSS or stack.

Tested on STM32F072.

66aa53873f usbd_gs_can: USBD_GS_CAN_Config_Request(), USBD_GS_CAN_Config_Request(): sort switch statements 
In USBD_GS_CAN_Config_Request(), sort the switch statement by
GS_USB_BREQ vlaue as much as possible, but don't duplicate code.

First place the "Host -> Device" calls which use USBD_CtlPrepareRx().
Followed by the "Device -> Host" calls which are using
USBD_CtlSendData().

For USBD_GS_CAN_EP0_RxReady(), simply sort by GS_USB_BREQ value.
