Provide simple wrappers for base/time types in WTF

- WTF::TimeDelta aliased base::TimeDelta
- WTF::{Time,TimeTicks} are a thin wrapper around base::{Time,TimeTicks} this is
  mainly because we want to control the API surface we expose in particular we
  want to avoid exposing string parsing functions at this time.

Once we have these types we can start replacing usage of double and int to
represent time in blink with more accurate and type safe representations.

esprehn@: PTAL and let me know if this approach makes sense.

This is an example of a follow up patch the uses these new 
types to improve the time type in PlatformEvents
