gh-129748: Update mimalloc to use atomic store for mi_block_set_nextx (GH-134238)
(cherry picked from commit 317c496223)

If the error handler is used, a new bytes object is created to set as
the object attribute of UnicodeDecodeError, and that bytes object then
replaces the original data. A pointer to the decoded data will became invalid
after destroying that temporary bytes object. So we need other way to return
the first invalid escape from _PyUnicode_DecodeUnicodeEscapeInternal().
_PyBytes_DecodeEscape() does not have such issue, because it does not
use the error handlers registry, but it should be changed for compatibility
with _PyUnicode_DecodeUnicodeEscapeInternal().

The 'help("topics")' output was misaligned due to "ASSIGNMENTEXPRESSIONS"
exceeding the implicit maximum default column width of 19 characters.
Reduced the number of columns from 4 to 3 in the listtopics()
function to allow more space for longer topic names.

In 3.13.3 we accidentally broke the interface for custom task factory. Factory authors added workarounds.
This PR (for 3.13.4) unbreaks task factories that haven't made a workaround yet while also supporting those that have.
NOTE: The custom task factory API will change to what we accidentally released in 3.13.3.

This fixes a crash in `_PyObject_TryGetInstanceAttribute` due to the use
of `_PyDictKeys_StringLookup` on an unlocked dictionary that may be
concurrently modified.
The underlying bug was already fixed in 3.14 and the main branch.
