cmd/gomobile: concurrent build for iOS archive files
This change makes building archive files for iOS concurrent for each
architecture and each platform. The strategy is basically the same as
my previous CL for Android: https://go.dev/cl/426274.
This change also specifies GOMODCACHE explicitly when executing Go
commands so that the existing cache is always used. The default
GOMODCACHE is $GOPATH/pkg/mod, and this path varies when a temporary
GOPATH is specified, which results in cold cache.
Before this change (on my MacBook Pro 2020):
$ time go run ./cmd/gomobile/ bind -target ios ./example/bind/hello/
real 0m23.274s
user 0m15.751s
sys 0m10.469s
After this change:
$ time go run ./cmd/gomobile/ bind -target ios ./example/bind/hello/
real 0m8.059s
user 0m13.763s
sys 0m9.004s
Updates golang/go#37902
Updates golang/go#54770
