qemurunner: Add info log for qemu startup

Browse Source 
Add a couple of logging info to track time between activities, first
is from after the Popen(launch_cmd) to after qmp.connect(), second is
from qmp.connect() to the release of the qemu via the qmp("cont") command
this includes the mmap() activity.

Example output:
QMP connected to QEMU at 06/24/21 11:11:56 and took 0.9556229114532471 seconds from launch
QMP released QEMU at 06/24/21 11:11:56 and took 0.26789021492004395 seconds from connect

(From OE-Core rev: 547f49230ba4ebeefe5b696e0460ebaffa8e91e6)
