This adds an ExecutionSignature tag named Device that passes the
DeviceAdapterTag as an argument to the worklet's operator(). This allows
worklets to specialize their code based on the device.

All of the methods in CellLocatorBoundingIntervalHierarchy were listed in
header files. This is sometimes problematic with virtual methods. Since
everything implemented in it can just be embedded in a library, move the
code into the vtkm_cont library.

Now that UInt8 has become part of the list of default types compiled,
there have been numerous warnings that have popped up about converting
ints to unsigned char. The reason for these is when you do arithmetic
(+, -, *, or /) on a char or short, it is automatically upconverted to a
32-bit integer. When you then try to set that back to a smaller integer,
you get a conversion warning.
This change gets around this problem by explicitly telling the compiler
we expect this type with static_cast. We have also talked about
disabling conversion warnings, but this has not happened on all
dashboards, and it is not that hard to work around the warning.
Mask objects allow you to specify which output values should be
generated when a worklet is run. That is, the Mask allows you to skip
the invocation of a worklet for any number of outputs.
For some reason, these changes caused one of the CUDA compilers to
create an error about a variable declared constexpr not being available
on the device. That sounds like a bug in nvcc as the constexpr should
just be evaluated rather than stored in some part of memory. At any
rate, changing the constexpr to a preprocessing macro solves the
problem.
The timer class now is asynchronous and device independent. it's using an
similiar API as vtkOpenGLRenderTimer with Start(), Stop(), Reset(), Ready(),
and GetElapsedTime() function. For convenience and backward compability, Each
Start() function call will call Reset() internally and each GetElapsedTime()
function call will call Stop() function if it hasn't been called yet for keeping
backward compatibility purpose.
Bascially it can be used in two modes:
* Create a Timer without any device info. vtkm::cont::Timer time;
* It would enable timers for all enabled devices on the machine. Users can get a
specific elapsed time by passing a device id into the GetElapsedtime function.
If no device is provided, it would pick the maximum of all timer results - the
logic behind this decision is that if cuda is disabled, openmp, serial and tbb
roughly give the same results; if cuda is enabled it's safe to return the
maximum elapsed time since users are more interested in the device execution
time rather than the kernal launch time. The Ready function can be handy here
to query the status of the timer.
* Create a Timer with a device id. vtkm::cont::Timer time((vtkm::cont::DeviceAdapterTagCuda()));
* It works as the old timer that times for a specific device id.
