Disable fuchsia-related checks in clang-tidy

Compiling the demos leads to a lot of warnings from clang-tidy, many of which are from the Fuchsia warning set, such as "fuchsia-default-arguments". Fuchsia has a very specific style guide which is not generally appropriate, e.g., calling functions with default arguments is valid C++ practice, but disallowed by Fuchsia.

I would suggest the following list instead of "" as used currently:
bugprone-,cert-,clang-analyzer-,cppcoreguidelines-,google-,hicpp-,llvm-,misc-,modernize-,performance-,readability-

Opinions?
