Update reclient version, allow mac to checkout reclient, add mac builder

Mac builder added per https://chromium-review.googlesource.com/c/v8/v8/+/3755921/comments/dc378d70_002b4107

Bump the re-client version to match the same one chromium is currently using: https://source.chromium.org/chromium/chromium/src/+/main:DEPS;l=265;drc=11428e8ebaf6a78020d442da479b5b0daa0dffb5

The older version of re-client 0.40.0.40ff5a5 will not work when attempting to use it in a recipe targeting mac

The version bump has been tested successfully with V8 Official Linux64 (reclient) https://ci.chromium.org/raw/build/logs.chromium.org/v8/led/richardwa_google.com/dd361303d10e4d506bd31e16ca73bdef6183e622f55493f90d9c152195c5c4fc/+/build.proto?server=chromium-swarm.appspot.com and V8 Linux64 - builder (reclient) https://ci.chromium.org/raw/build/logs.chromium.org/v8/led/richardwa_google.com/758cd57ad9ee572bcfe339a2435eb82e1028e72bf74a7b57cabfd616ffad1e28/+/build.proto?server=chromium-swarm.appspot.com
