    c++: Fix poor diagnostic for array initializer [PR93710]

    A small improvement for an error in build_user_type_conversion_1:
    instead of

    array-init1.C:11:1: error: conversion from ‘long int’ to ‘A’ is ambiguous
       11 | };
          | ^

    we will print

    array-init1.C:8:3: error: conversion from ‘long int’ to ‘A’ is ambiguous
        8 |   0L,
          |   ^~

        PR c++/93710 - poor diagnostic for array initializer.
        * call.c (build_user_type_conversion_1): Use cp_expr_loc_or_input_loc
        for an error call.

        * g++.dg/diagnostic/array-init1.C: New test.
