* Roll Fuchsia buildtools to 85907c59e97527d79bbfdfd849d8e85c24959cc5 This also updates Flutter buildroot to a6e52dbb776c45cc8c57d7143b8eb8b2e762fdfb which disables -Wtautological-constant-compare temporarily until https://reviews.llvm.org/D39462 lands in clang. This is in line with Fuchsia's compiler options. * Apply clang-format diffs No logical changes. This applies clang-format from the latest Fuchsia buildtools to the engine codebase.
