Addresses #95512 (comment).

When a custom sysroot is requested, then don't error when translation resources are not found, only warn.

rustc_interface has this fallback logic for codegem backends: https://github.com/rust-lang/rust/blob/master/compiler/rustc_interface/src/util.rs#L272

Changed the approach this PR takes to use sysroot_candidates.

LGTM, but I would like someone else to review too.

Is this testable by just pointing a ui test to an empty directory or will that fail earlier due to other things?

Instead of checking only the user provided sysroot or the default (when
no sysroot is provided), search user provided sysroot and then check
default sysroots for locale requested by the user.

I've added some more tests that I think cover most of the cases modified in this PR, more testing will be required when we actually have other translations and this mechanism is useful though.

I don't think pointing the sysroot at an empty directory is too helpful because it'll still check the default sysroot (which may contain a locale?) after that, so I've just tested that by checking for Klingon translations, assuming that we won't have that (knowing full well that someone might go away and do that translation just because this test depends on it not existing and I'm pretty okay with that).

I didn't use UI tests because we don't have a way to refer to get the path of a non-Rust auxiliary file like a custom Fluent resource, we've never needed that before.
