Let's wait with lldb testing until the test works properly with gdb.

Rollup merge of #144497 - Enselic:basic-stepping, r=Mark-Simulacrum tests: Add test for basic line-by-line stepping in a debugger Let's wait with lldb testing until the test works properly with gdb. This is a regression test to prevent further regressions of #33013 which unfortunately regressed in **nightly-2023-04-24**. See #33013 (comment).

tests/debuginfo/basic-stepping.rs: Remove ignore-aarch64 This test passes for me both with `gdb` and `lldb` when I run it on an aarch64 machine (namely [dev-desktop-eu-1](https://forge.rust-lang.org/infra/docs/dev-desktop.html)). And as can be seen below, it now passes PR CI, including **aarch64-gnu-llvm-21-1**. This test used to [fail](#144497 (comment)) PR CI, in particular **aarch64-gnu-llvm-19-1**. I suggest we put this in a rollup as an iffy PR to see if we can get it through. If we can, we are one step closer towards closing #33013.

triagebot.toml: Ping Enselic when tests/debuginfo/basic-stepping.rs changes The test `tests/debuginfo/basic-stepping.rs` has a history of [regressing for subtle reasons](rust-lang#33013 (comment)) ([retroactively](rust-lang#144497)), and has [expected behavior](rust-lang#153941) that is [not obvious](rust-lang#155377). So I'd like to keep an extra eye one it.
