When building for macOS and configured with target_cpu =
"mac_universal", bi-architecture x86_64/arm64 output will be produced.
mac_universal is, so far, a “Crashpad special” that will only work with
mini_chromium and the standalone Crashpad build, and not the in-Chromium
build. It exists to support Keystone, which intends to ship as
x86_64/arm64 universal.
Includes:
Update mini_chromium to e0008f2714a76c7f2a3854fa75774427a886d6b9
e0008f2714a7 mac-arm64: Allow target_cpu = "mac_universal" to create
universal builds
