usb: introduce UsbDataSessionMonitor class
Migrate the usb data session event functions to the class with the following additional functionalities; - Support detecting gadget soft pulldown (usually done during configfs function switch) and report usb data session correctly. - Support reporting usb data compliance warnings to the class USB by providing getDataComplianceWarnings call. - Use boot_clock instead of steady_clock to measure time correctly in the case of system suspend. UsbDataSessionMonitor is self-contained and can be migrated to pixel usb library after feature maturation. Bug: 297224564 Bug: 296119135 Test: usb data session upload in device and host mode Change-Id: Iba001933e193935d64cf5fd0a1257d02a4274fb1 (cherry picked from commit ea65ca11f6fbb6f13b89ef9ed03015f47ec1cedb)
