Feng Tian 3cf6450eb5 MdeModulePkg/Usb: Adjust TPL to not block async transfer during usb enum.
EDKII usb stack is using a TPL_CALLBACK timer to monitor async transfer
request and signal event if it's done. As usb enumeration and usb mass
storage block i/o read/write runs on TPL_CALLBACK and TPL_NOTIFY level
respectively, It blocks usb async transfer requests, usually usb mouse
/use kb, getting time to run.

Without this change, user couldn't get usb mouse/kb state in time (will
show a little lag from UI view) when there is other usb transactions, such
as a new usb device inserted.
