Previously, the `VTKM_ALWAYS_EXPORT` and `VTKM_NEVER_EXPORT` macros
used the gnu-specific `__attribute__` keyword. This change instead
uses the C++11 standard method of using `[[ ]]` as attributes.
Specifically, `__attribute(visibility("---"))` is changed to
`[[gnu::visibility("--")]]`.
The main impetus for this change is that `__attribute__` does not
seem to work with `[[deprecated]]` on GCC compilers. (For sure on
GCC 6. I didn't check all compiler versions.) This change was
recommended from
https://stackoverflow.com/questions/40886628/deprecated-attribute-visibility-default-in-gcc-6-2
This creates a minor backward incompatibility. We have always meant
for these macros to be used before the return type when used with
a function. However, GCC accepted placing `__attribute__` after
the return type. The C++11 `[[ ]]` cannot be placed there, so
some macros might have to be moved. Still, this was a broken
use that happened to work.
