clang-format: Add CompactNamespaces option

Summary:
Add CompactNamespaces option, to pack namespace declarations on the
same line (somewhat similar to C++17 nested namespace definition).

With this option, consecutive namespace declarations are kept on the
same line:

  namespace foo { namespace bar {
      ...
  }} // namespace foo::bar
