Subject: [PATCH] feat(cli): allow to build without upgrade feature

The self-upgrade feature is undesirable when deno is installed from
(Linux) distribution repository - using a system package manager.
This change will allow package maintainers to build deno with the
"upgrade" subcommand and background check disabled.

When the user runs `deno upgrade <args>` and the upgrade feature is
disabled, it will exit with error message explaining that this deno
binary was built without the upgrade feature.

Resolves #19909
