Implement more modifier queries for getModifierState on Keyboard/Mous…

…e events.

Include support for querying:
Accel, AltGraph, CapsLock, Fn, NumLock, OS, ScrollLock, Symbol

A large portion of this change is cleaning up how the modifiers are passed
into event construction. Instead of passing 4 booleans; try to pass the
event flag mask or the EventModifierInit dictionary directly.

See intent to ship:
https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/3mwQZ2wdy18

Not all platforms currently are setting the flags appropriately on the
constructed WebInputEvents; this will be done in a follow-up change.
