Add constants which provide information about the version of the
compression library used for building the module and the version
actually loaded:

* zlib: ZLIB_VERSION_INFO, zlib_version_info, ZLIBNG_VERSION_INFO,
  and zlib_version as an alias of ZLIB_RUNTIME_VERSION
* bz2: bzlib_version, bzlib_version_info
* lzma: LZMA_VERSION, lzma_version, LZMA_VERSION_INFO, lzma_version_info
* compression.zstd: ZSTD_VERSION, ZSTD_VERSION_INFO

Make compression.zstd.zstd_version_info a named tuple.

…ol_id (python#156706)

pythongh-116750: Document versionadded/versionchanged for sys.monitoring tool_id functions

clear_tool_id() was added in 3.14 but lacked a versionadded note, and
free_tool_id()'s behavior change (now calling clear_tool_id() before
releasing the tool_id, rather than leaving events/callbacks registered)
was undocumented. Also add a What's New in 3.14 entry for both.
