vkjson: Add .clang-format

Future changes to vkjson should use consistent code formatting. The
vkjson-specific .clang-format will define the style to be used; I
picked Chromium style because it's the closest to the style of the
current code.

To avoid polluting git history/blame, I'm not reformatting all of the
existing code at this point. New changes should be run through
git-clang-format to reformat any modified lines. Recommended
configuration is:

  git config clangFormat.style file
  git config clangFormat.extension h,cc

diff --git a/libs/vkjson/.clang-format b/libs/vkjson/.clang-format
