Ruby <2.7 does not allow non-finalizable objects to be WeakMap
keys: https://bugs.ruby-lang.org/issues/16035
We work around this by using a secondary map for Ruby <2.7 which
maps the non-finalizable integer to a distinct object.
For now we accept that the entries in the secondary map wil never
be collected. If this becomes a problem we can perform a GC pass
every so often that looks at the contents of the object cache to
decide what can be deleted from the secondary map.
The #ifdef block is duplicated with the above (which was fixed in 3.15.1).
It would be great to have this fix backported to 3.15.1 (and released as 3.15.2).
Since the keys are `Class`-s, there's no need to hash/copy/etc. them. This
avoids causing `+initialize` on the classes just when building up a registry.

Our use of constinit does not seem to work with GCC yet (see
https://github.com/protocolbuffers/protobuf/issues/8310), so this
commit disables it on GCC for now.
This commit also updates mutex.h to work around the fact that MinGW's
std::mutex apparently does not have a constexpr constructor. We already
have this kind of workaround for MSVC, so we can just use the same
workaround.
Some of our Kokoro builds have been failing because Kokoro is unable to
copy root-owned files when the build is complete. This commit fixes the
problem by deleting these files at the end.
The installation of apt-transport-https is failing and causing this
script to exit early. I suspect the package is no longer needed since
recent versions have moved it into the apt package, so this change
updates the script to stop trying to install apt-transport-https.
* Create jvm_native_images.md
Some initial text pertaining to the use of protobuf with AOT compilation tools such as the one provided by GraalVM native-image.
* Update jvm_native_images.md
Fixed spelling
* Update and rename jvm_native_images.md to jvm_aot.md
