Updated all host mode demos and projects to use the EVENT_USB_Host_DeviceEnumerationComplete() event callback for device configuration instead of manual host state machine manipulations in the main application task.

Browse source 
Added new USB_Host_ConfigurationNumber global variable to indicate the selected configuration in an attached device.

Renamed global state variables that are specific to a certain USB mode to clearly indicate which mode the variable relates to, by changing the USB_* prefix to USB_Device_* or USB_Host_*.

Removed the HOST_STATE_WaitForDeviceRemoval and HOST_STATE_Suspended host state machine states, as these are no longer required.

Altered the USB_Host_SetDeviceConfiguration() function to update the new USB_Host_ConfigurationNumber global as required.

Moved out the Host mode standard request convenience/helper functions from the architecture specific Host driver files to the architecture agnostic HostStandardReq.c driver file.

* - The device mode Audio class driver now requires a new user application callback, \ref CALLBACK_Audio_Device_GetSetEndpointProperty().
* Existing applications must implement this new callback, however if multiple sample rates or pitch control is not used,
* this function may be hard-coded to always return false for previous behaviour to be retained.
* - The \c USB_ConfigurationNumber, \c USB_RemoteWakeupEnabled and \c USB_CurrentlySelfPowered globals have been renamed to
* \ref USB_Device_ConfigurationNumber, \ref USB_Device_RemoteWakeupEnabled and \ref USB_Device_CurrentlySelfPowered to clearly indicate
* the USB mode they relate to. Existing applications using these variables should rename all references to the previous names.

* - The USB_Host_SetDeviceConfiguration() function now automatically sets the USB Host state machine to the \ref HOST_STATE_Configured
* state if a non-zero configuration is set sucessfully, or the \ref HOST_STATE_Addressed if a zero-index configuration is specified. Existing
* applications should no longer manually alter the \ref USB_HostState global, and should instead call this function to configure and
* unconfigure an attached device.
* - The \c HOST_STATE_WaitForDeviceRemoval and \c HOST_STATE_Suspended host state machine states have been removed; these are replaced by
* unconfiguring the attached device via a call to \ref USB_Host_SetDeviceConfiguration() and a test of \ref USB_Host_IsBusSuspended() instead.
* - It is highly recommended that the EVENT_USB_Host_DeviceEnumerationComplete() event callback now be used for initial device configuration,
* rather than a switch on the USB host state machine state for readability.
