* Windows: Read ENV names and values as UTF-8 encoded Strings
Implements issue #12650: fix https://bugs.ruby-lang.org/issues/12650
This also removes the special encoding for ENV['PATH'] and some
complexity in the code that is unnecessary now.
* Windows: Improve readablity of getenv() encoding
getenv() did use the expected codepage as an implicit parameter of the macro.
This is mis-leading since include/ruby/win32.h has a different definition.
Using the "cp" variable explicit (like the other function calls) makes it
more readable and consistent.
* Windows: Change external C-API macros getenv() and execv() to use UTF-8
They used to process and return strings with locale encoding,
but since all ruby-internal spawn and environment functions use UTF-8,
it makes sense to change the C-API equally.
* Use UTF-8 as default for Encoding.default_external on Windows
* Document UTF-8 change on Windows to Encoding.default_external

Although gemspec file (e.g., power_assert and rake) often uses
`git ls-files`, as it does not make sense in other than its own
repository, it has been ignored now. Gather all files expanded
from the bundled gem to install, instead.
Thread's interrupt set Ractor's wakeup_status as interrupted, but
the status remains next Ractor communication API. This patch makes
to ignore the previous interrupt state.
[Bug #17366]
Also this patch solves the Thread#kill and Ractor#take issues.
getaddrinfo_a() gets stuck after fork().
To avoid this, we need 1 second sleep to wait for internal
worker threads of getaddrinfo_a() to be finished, but that is unacceptable.
[Bug #17220] [Feature #17134] [Feature #17187]
Write barrier requires VM lock because it accesses VM global bitmap
but RB_VM_LOCK_ENTER() can invoke GC because another ractor can wait
to invoke GC and RB_VM_LOCK_ENTER() is barrier point. This means that
before protecting by a write barrier, GC can invoke.
To prevent such situation, RB_VM_LOCK_ENTER_NO_BARRIER() is introduced.
This lock primitive does not become GC barrier points.
On windows, MJIT doesn't work without this patch because of
the declaration of ruby_single_main_ractor. This patch fix this
issue and move the definition of it from ractor.c to vm.c to locate
near place of ruby_current_vm_ptr.
Now object allocation requires VM global lock to synchronize objspace.
However, of course, it introduces huge overhead.
This patch caches some slots (in a page) by each ractor and use cached
slots for object allocation. If there is no cached slots, acquire the global lock
and get new cached slots, or start GC (marking or lazy sweeping).
Without this patch, Ruby doesn't show ractor's information when
there is only 1 ractor. However it is hard to read the log when
some ractors are created and terminated. This patch makes to keep
showing ractor's information on multi-ractor mode.
accessing theap needs complicating synchronization but it reduce
performance on multi-ractor mode. So simply stop using theap
on multi-ractor mode. In future, theap should be replaced with
more cleaver memory strategy.
ruby_multi_ractor was a flag that indicates the interpreter doesn't
make any additional ractors (single ractor mode).
Instead of boolean flag, ruby_single_main_ractor pointer is introduced
which keeps main ractor's pointer if single ractor mode. If additional
ractors are created, ruby_single_main_ractor becomes NULL.

Previously, rb_getaddrinfo_a_before_exec() is called from before_exec().
However, the function needs to be called only before fork().
The change moves it to before_fork().
* This reverts commit b06ffce4aef002dc47c3c5968181230e7ab8d7cc.
* Do not revert specs, wrap them with `ruby_version_is` (tool for that in next commit).
