E0040 needs to be updated to new format

[sophiajt]

From: src/test/compile-fail/E0040.rs

Error E0040 needs a span_label, updating it from:

error[E0040]: explicit use of destructor method
  --> src/test/compile-fail/E0040.rs:23:7
   |
23 |     x.drop(); //~ ERROR E0040
   |       ^^^^

error: aborting due to previous error

To:

error[E0040]: explicit use of destructor method
  --> src/test/compile-fail/E0040.rs:23:7
   |
23 |     x.drop(); //~ ERROR E0040
   |       ^^^^ call to destructor method

error: aborting due to previous error

Should be fixed by #35357.
