sam marshall 81b4f04fb3 MDL-74960 core\lock: Performance info - display lock performance ...

Show performance information about locks (time taken to acquire lock,
time lock is held for) in the 'perfinfo' display.

Also show existing information (that was already calculated but not
shown before) about the session lock, which is not a 'core\lock' type
lock, but the information is similarly useful.
