feat(usb_host): MSC Host add suspend/resume events

[peter-marcisovsky]

Description

This MR adds Suspend/Resume events for MSC class driver as a follow-up for the Global/Suspend resume MR in esp-idf.

Added a backward compatibility for older IDF releases, where the suspend/resume will not be backported, by:

// For backward compatibility with IDF versions which do not have suspend/resume api
#ifdef USB_HOST_LIB_EVENT_FLAGS_AUTO_SUSPEND
#define MSC_HOST_SUSPEND_RESUME_API_SUPPORTED
#endif
