Interval + CSV time-profiling

This PR fixes #10886. The -p option can be followed by either an interval number or a CSV filename.
* In the interval profiling, the profiler output would be spitted out to the terminal periodically.
Example usage: **./mach run -p 1 http://www.google.com** will print the time-profiling output to the terminal every second.

* In the CSV file profiling, a CSV file will be generate upon termination of servo.
Example usage: **./mach run -x -o out.png -p out.csv http://www.google.com** will generate out.csv upon termination of Servo.
