fix: canonicalize @platforms//cpu:aarch64 (#3555)

This is defined as an alias to :arm64:
https://github.com/bazelbuild/platforms/blob/212a486d66569b29c95b00364e2584e80fd08614/cpu/BUILD#L16-L20
but toolchain resolution doesn't understand the two to be equivalent.

Fixes aspect-build/rules_js#469
