Deprecate SPT threading support on NonStop. 

This fix removes explicit support for the SPT threading model in configurations.
This also reverts commit f63e1b48ac that were
required for SPT but broke other models.

Fixes: #22798

Threading Models
----------------
OpenSSL can be built using unthreaded, POSIX User Threads (PUT), or Standard
POSIX Threads (SPT). Select the following build configuration for each on
the TNS/X (L-Series) platform:
OpenSSL can be built either using the POSIX User Threads (PUT) threading model,
or with threading support disabled. Select the following build configuration
for each on the TNS/X (L-Series) platform:
* `nonstop-nsx` or default will select an unthreaded build.
* `nonstop-nsx` or default will select an unthreaded 32-bit build.
* `nonstop-nsx_64` selects an unthreaded 64-bit memory and file length build.
* `nonstop-nsx_put` selects the PUT build.
* `nonstop-nsx_64_put` selects the 64 bit file length PUT build.
* `nonstop-nsx_spt_floss` selects the SPT build with FLOSS. FLOSS is
required for SPT builds because of a known hang when using SPT on its own.
* `nonstop-nsx_64_put` selects the 64-bit memory and file length PUT build.
The SPT threading model is no longer supported as of OpenSSL 3.2.
### TNS/E Considerations

- nonstop-nsx_64_put
**Note:** Cross-compile builds for TNS/E have not been attempted, but should
follow the same considerations as for TNS/X above. SPT builds generally require
FLOSS, which is not available for workstation builds. As a result, SPT builds
of OpenSSL cannot be cross-compiled.
