rustc: Simplify getting sysroot library directory #129418

It was very non-obvious that sess.target_tlib_path, make_target_lib_path(...), and sess.target_filesearch(...).search_paths() result in the same sysroot library directory paths.
They are however, indeed the same, because sess.target_tlib_path is initialized to make_target_lib_path(...) on Session creation, and they are used interchangeably.

There are still some redundant calls to make_target_lib_path and other inconsistent ways to obtain sysroot directories, but fixing that requires some behavior changes, while this PR is a pure refactoring.
Some places in the compiler even disagree on the number of sysroots - 1 (explicit --sysroot or default sysroot), 2 (explicit --sysroot and default sysroot), or an unclear number of sysroot_candidates every of which is considered.
The logic currently using sess.target_tlib_path or equivalents assumes one sysroot.

Thanks, using different variations to arrive at the same search dir is indeed very confusing...
