We can install RubyGems plugin by "gem install XXX". The installed
plugin is used from the NEXT "gem ...".
For example, "gem install gem-src kaminari" doesn't use gem-src plugin
for kaminari. "gem install gem-src && gem install kaminari" uses
gem-src plugin for kaminari.
How about loading a plugin immediately when the plugin is installed?
If this proposal is implemented, "gem install gem-src kaminari" works
like "gem install gem-src && gem install kaminari".

If `bundler _<version>_` is given, I guess the most reasonable approach
is to completely skip version switching, because the user is technically
opting out of it. But since binstubs completely remove this argument
from `ARGV` after processing it, we have no way of detecting that it was
actually passed in the first place in order to skip the feature. So we
set `BUNDLER_VERSION` explicitly in this case.

When bundler parallel installer installs gems concurrently, one can get
confusing warnings like the following:
```
"[/home/runner/work/rubygems/rubygems/bundler/tmp/2/gems/system/specifications/zeitwerk-2.4.2.gemspec] isn't a Gem::Specification (NilClass instead).
```
I've got these warnings several times in the past, but I never managed
to reproduce them, and never look deeply into the root cause, but this
time a got a cause that reproduced quite frequently, so I looked into
it.
The problem is one thread reading a gemspec while another thread is
writing it. The write of the gemspec was not protected, so
`Gem::Specification.load` could end up seeing a truncated gemspec and
thus throw this warning.
The fix involve two changes:
* Change the methods that write gemspecs to use `Gem.binary_write` which
is protected by a lock.
* Fix `Gem.binary_write` to create the file lock at file creation time,
not when the file already exists after.
The realworld user problem caused by this issue happens in bundler, but
I'm fixing it in rubygems first, and then I'll backport to bundler
whatever needs backporting to fix the issue on the bundler side.

This reverts commit af604436d8141c34cb2e1e645b9b0d47bfd55a55.
The issue that led to introducing it was never reproduced. I tried to
repro with this patch and it still works just fine. Since this removal
is getting in the middle for some race conditions I'm facing, I'm
reverting the patch.

Fixes the `Gem::FilePermissionError` without the privilege.
Initialize `@plugins_dir` to the user gem directory, when
installing with `--user` option.

It seems like the most common case since it requires no tricks on our
CI environment.
