[Python] Improve repr of pyarrow.compute.FunctionOptions #28921
Description
ARROW-13025 added a ToString which is now used in the Python repr. This adds the specified parameters nicely, but I would be useful to still include the name of the class as well:
In [9]: pc.TrimOptions("a")
Out[9]: {characters="a"}Reporter: Joris Van den Bossche / @jorisvandenbossche
