Commit ac21c1780a63a8d9a3a6217eb52fe0d188fa7655 VMS knows POSIX threads too!
removed ossl_crypto_mem_barrier for POSIX systems.

Remove it for Win32 and other architectures as well.

Resolves issue #19506 Unable to build under bcc32c environment (Embarcadero
clang compiler).

crypto: thread: serialize concurrent joins

Multiple concurrent joins with a running thread suffer from a race
condition that allows concurrent join calls to perform concurrent arch
specific join calls, which is UB on POSIX, or to concurrently execute
join and terminate calls.

As soon as a thread T1 exists, one of the threads that joins with T1
is selected to perform the join, the remaining ones await completion.
Once completed, the remaining calls immediately return. If the join
failed, another thread is selected to attempt the join operation.

Forcefully terminating a thread that is in the process of joining
another thread is not supported.

Common code from thread_posix and thread_win was refactored to use
common wrapper that handles synchronization.

crypto: add preemptive threading support

Some primitives are designed to be used in a multi-threaded environment,
if supported, e.g., Argon2.

This patch adds support for preemptive threading and basic synchronization
primitives for platforms compliant with POSIX threads or Windows CRT.
Native functions are wrapped to provide a common (internal) API.

Threading support can be disabled at compile time. If enabled, threading
is disabled by default and needs to be explicitly enabled by the user.

Thread enablement requires an explicit limit on the number of threads that
OpenSSL may spawn (non-negative integer/infinity). The limit may be changed.
