tex-mathtools: update to 1.31

For mathtools.dtx v1.31
* Fixed bug in the mathic option, initially reported in private email by
  Lorents Landgren.

  A scratch counter was not properly initialised causing penalties to be
  inserted where they should not.

  Note that this fix is likely to change line breaks in existing documents
  that uses the mathic option.

For empheq.dtx v2.17
* Fixed typo in manual reported by campa

Log message:
tex-mathtools: update to 1.30

* Added a caveat about \xmapsto when ever unicode-math is loaded.
  The macro does not work as the symbol marking the bar at the start
  is not available under unicode-math.

* Added a default \MT_active_colon_false: for when centercolon=true
  has never been executed

* Gave \DeclarePairedDelimiter... support for the empty scaler (dot)

* Added \xLongrightarrow and \xLongleftarrow

* Added a bracing group inside \newtagform such that the inner format
  only applies to the number

Log message:
tex-mathtools: update to 1.29

* In section `Special mathtools options` clearified when `gathered` of pure
amsmath might give a warning.
* Added 3.6 note 3: about \section{foo $\norm[\big]{bar}$}.
* Renamed a few colon combo symbols and added a few extra for completeness.
  A package option is available to revert the change.
* Added a warning if mathtools is loaded *after* `unicode-math`

Please note that this is a **breaking** change! For many years mathtools have
provided some colon related symbols, like :=. The names of which was copied from
txfonts/pxfonts. It turned out that these names were inconsistent, for example
\coloneq would be :- where as \coloneqq would be :=. This has now been changes
such that both provides :=. Additional colon symbols have also been added. If
needed, the package option legacycolonsymbols will revert the old behaviour of
\coloneq, \Coloneq, \eqcolon and \Eqcolon.

With manual adjustments afterwards since pkglint 19.4.4 fixed a few
