What does this PR try to resolve?

Fixes #17255.

The profile_trim_paths::object_works tests run the packed and unpacked cases on every Linux host. However, some Linux targets, including riscv64gc-unknown-linux-gnu, currently report only off from rustc --print=split-debuginfo.

Cargo correctly avoids passing an unsupported -Csplit-debuginfo value to rustc. The tests nevertheless expect that argument in the verbose command output, causing both cases to fail on those hosts.

This reuses the requires_host_split_debuginfo test requirement for the packed and unpacked cases. Unsupported hosts now report the tests as ignored with the capability as the reason, while the off case continues to provide trim-paths=object coverage. If rustc later advertises support for either mode, the corresponding test will automatically run again.

How to test and review this PR?

Review that only the packed and unpacked Linux tests are gated, and that the off test remains unconditional.

Tested from src/tools/cargo in a rust checkout with:

../../../build/x86_64-unknown-linux-gnu/rustfmt/bin/rustfmt --check tests/testsuite/profile_trim_paths.rs
RUSTC=../../../build/x86_64-unknown-linux-gnu/stage2/bin/rustc cargo test --test testsuite profile_trim_paths::object_works:: -- --nocapture

All three cases pass on an x86_64 Linux host that supports off, packed, and unpacked.

The RISC-V target capability was checked with:

../../../build/x86_64-unknown-linux-gnu/stage2/bin/rustc --target riscv64gc-unknown-linux-gnu --print=split-debuginfo
off

Ah. Nice. I forgot we already have that requires_host_split_debuginfo. Thanks!
