Use RubyGems facilities to install Gems during Ruby installation
tools/rbinstall uses quite some custom code to install gems instead of using functionality available in RubyGems. I don't think this is good, because the code is non transparent ATM and it is duplicating functionality, which is already available and tested in RubyGems. Also, it intoduces its own concepts such as
$prog_mode. So I opened two PRs, gradually implementing this.
The first PR 1 uses

- It avoids deprecated code paths in RubyGems 3.
The second PR 4 builds on the top of the first one and uses
UnpackedInstaller to install default gems (it would be probably nice to get
UnpackedInstaller into RubyGems, but I am not sure how it could be invoked). As a bonus, it removes the pregenerated binstubs. These are now generated by
