`ArrayHandle::DeepCopy` creates a new `ArrayHandle` of the same type and
deep copies the data into it.
This functionality is similar to `ArrayCopy`. However, it can be used
without having to compile for the device on which the copy happens.
Now that the data in an `ArrayHandle` is stored in `Buffer` objects, we
now have a more efficient way of doing deep copies of memory. Rather
than call `Algorithm::Copy`, which iterates over the array and copies
each item, `ArrayCopy` now uses the `Buffer` interface to do direct
device-to-device (or host-to-host) mem copies. This should be more
efficent and take less time to compile.
Note that this direct `Buffer` copy only works if the two `ArrayHandle`s
are of the same type. If they are different, `ArrayCopy` still has to
fall back to using `Algorithm::Copy`.
Also note that not all `ArrayHandle`s are using the new `ArrayHandle`
interface (and therefore not using `Buffer` objects). Thus, a fallback
is still available for old `ArrayHandle` types.

The `ContourTreeUniformAugmented` tests for Cuda consistently
times out while running on the `centos7_gcc48` and `rhel8_test_centos7`
configurations. Temporarily exclude it to improve the CI turn-around time
while this issue is being resolved.
This has no real change in the operation, but it will simplify code as
we convert `ArrayHandle`s to the new type. We will be able to write
simple runtime code rather than complex metaprogramming to determine the
number of buffers to use.

Previously, most of the benchmarks just measured time spent reading or
writing the array on the device. The transfer only happened on the first
iteration and was then cached on the device.
This change clears out the array every iteration so that the array has
to be transferred afresh.
