Description of Change

Remote clang steps from macOS and Windows hosts run a Linux clang on the RBE workers through clang_remote_wrapper. That wrapper, the Linux clang download and the rewrapper_{mac,windows}.cfg Chromium's GN and siso config check for were the last things we still took from EngFlow's reclient-configs: a DEPS checkout, two patches on it, a Chromium patch chaining its generator behind Chromium's configure_reclient_cfgs hook, and CI steps that installed the reclient binaries and reran the generator on the macOS and Windows runners. Nothing runs reproxy or rewrapper anymore.

As of electron/build-tools#904, e sync and e build stage the Linux clang, install the wrapper and write the stub cfgs themselves, so this bumps BUILD_TOOLS_SHA to that merge and removes:

• the src/third_party/engflow-reclient-configs DEPS entry, patches/reclient-configs and its patches/config.json row
• build_run_reclient_cfg_generator_after_chrome.patch, and the EngFlow line from the third_party .gitignore patch
• fix-sync's "Fix reclient" and "Configure reclient configs" steps, and the matching steps in the macOS clang-tidy job, which now fetches the Linux clang-tidy after e build --gen=only has staged the Linux clang it sits next to

All four macOS and Windows build jobs and the macOS clang-tidy job pass here with e build staging the Linux clang itself; object change rate against main is 0.01-0.02%. The first builds miss the remote cache because the wrapper's contents changed.
