support for macOS arm64

[robs]

I've done some searching but have yet to see this issue tracked anywhere.

As most of you have probably heard, Apple announced at their WWDC that they are transitioning from Intel to "Apple Silicon" (arm64 architecture). I've been able to do some basic testing with their "Developer Transition Kit" (a mac mini with an arm64 architecture CPU). Launching Chrome on this machine crashes the helper in a call to "__mprotect":

A similar crash happens when using CEF based applications (including my own).

If someone can point me to where this is being tracked in Chromium I'd appreciate it. Also, if I can help test anything out related to CEF support for this please let me know.

Thanks,
Rob
