Feature: Add flags to stopwatch to track multiple listings.

Description

Currently we can only pause or break the single stopwatch. Adding this feature allow you to also save particular time marks while the stopwatch is still going on. This will allow recording of multiple time stamps simultaneously.

Hey, if you are planning to work on this feature
please consider to implement responsiveness in the whole stopwatch page since the height and width are hardcoded

@ganidande905 Thanks for pointing this out. I'll try to refactor the code in the stopwatch page to make it responsive. @AryanSarafDev I'd like to work on this.
