Brief description of what is fixed or changed

fixes #25827
simplify works on the other expression because of _eval_simplify. The problem is that Xor._eval_simplify doesn't call super()._eval_simplify, unlike And._eval_simplify and Or._eval_simplify, which calls simplify_logic.

#### Release Notes

<!-- Write the release notes for this release below between the BEGIN and END
statements. The basic format is a bulleted list with the name of the subpackage
and the release note for this PR. For example:

* solvers
  * Added a new solver for logarithmic equations.

* functions
  * Fixed a bug with log of integers. Formerly, `log(-x)` incorrectly gave `-log(x)`.

* physics.units
  * Corrected a semantical error in the conversion between volt and statvolt which
    reported the volt as being larger than the statvolt.

or if no release note(s) should be included use:

NO ENTRY

See https://github.com/sympy/sympy/wiki/Writing-Release-Notes for more

notes automatically to see if they are formatted correctly. -->
