Feature Request: Support for iOS Simulator ARM64

[dan-zozo]

I'm looking to build a fat Xcode xcframework via Bazel that pulls in cpuinfo as a dependency. When trying to build an iOS Simulator arm64 variation, I get the following error:

ERROR: <REDACTED>/cpuinfo/BUILD.bazel:100:11: configurable attribute "srcs" in @cpuinfo//:cpuinfo_impl doesn't match this configuration. Would a default condition help?
