console: use 'label' argument for time and timeEnd

Turns out the argument is actually called label in the console spec, while being wrongly named on MDN. This reverts commit 8c043c1. MDN has been updated in: https://developer.mozilla.org/en-US/docs/Web/API/Console/timeEnd$compare?locale=en-US&to=947893&from=918571 https://developer.mozilla.org/en-US/docs/Web/API/Console/time$compare?locale=en-US&to=947891&from=896987 PR-URL: #3590 Reviewed-By: targos - Michaël Zasso <[email protected]> Reviewed-By: James M Snell <[email protected]>

 Starts a timer that can be used to compute the duration of an operation. Timers
