cmd/release, dashboard: implement builder plan for Go 1.16

See https://golang.org/issues/40561#issuecomment-731482962
for the plan description and rationale.

Add new builder definitions that are needed for the plan.
Don't rely on generic builder name like "linux-amd64" to
avoid a repeat of golang.org/issue/31293; use a specific
builder name instead.

Remove support and test cases for Go 1.13, it's unsupported
per release policy.

For golang/go#40561.
