Merge bundler to standard libraries.
rubygems 2.7.x depends bundler-1.15.x. This is preparation for
rubygems and bundler migration.
* lib/bundler.rb, lib/bundler/*: files of bundler-1.15.4
* spec/bundler/*: rspec examples of bundler-1.15.4. I applied patches.
* https://github.com/bundler/bundler/pull/6007
* Exclude not working examples on ruby repository.
* Fake ruby interpriter instead of installed ruby.
* Makefile.in: Added test task named `test-bundler`. This task is only
working macOS/linux yet. I'm going to support Windows environment later.
* tool/sync_default_gems.rb: Added sync task for bundler.
[Feature #12733][ruby-core:77172]
