WTF::bind: Remove the need of hand-rolled code for bound arguments.
This patch adds a generalized version of PartBoundFunctionImpl for
WTF::bind(), and removes the hand-rolled code that contains the
repetition for cases with zero to seven bound arguments.
The key trick is to use std::tuple<T...> to pass the types of bound
parameters.
This patch adds a new dependency to base/tuple.h for a simple utility
called base::IndexSequence defined there. The bind code lives in WTF, so
this should be fine.
