Download external Go dependencies in build
This change updates the Go GN integration to download external
dependencies for Go packages before running "go build". These
dependencies are listed in the pw_go_package template using build
metadata and collected to a "go get" invocation.
To support this, the pw_exec template is expanded to allow setting
positional arguments from a file.
