Auto merge of rust-lang#88316 - est31:remove_box_tests, r=Mark-Simulacrum

Remove most box syntax uses from the testsuite except for src/test/ui/issues

Removes most box syntax uses from the testsuite outside of the src/test/ui/issues directory. The goal was to only change tests where box syntax is an implementation detail instead of the actual feature being tested. So some tests were left out, like the regression test for rust-lang#87935, or tests where the obtained error message changed significantly.

Mostly this replaces box syntax with `Box::new`, but there are some minor drive by improvements, like formatting improvements or `assert_eq` instead of `assert!( == )`.

Prior PR that removed box syntax from the compiler and tools: rust-lang#87781
