66742c2a - [E2E][sycl-rel 6.3] Make lit search tools in `bin/` directory (#20395)

[E2E][sycl-rel 6.3] Make lit search tools in `bin/` directory (#20395) Fixes E2E test failure in `SeperateCompile/test.cpp` in sycl-rel 6.3 ABI testing(https://github.com/intel/llvm/actions/runs/18599730732/job/53035028308#step:27:2964) The test failure is because of lit using system-installed `sycl-post-link` instead of the newly built one. This PR forces lit to find and use tools from `<compiler build>/bin` directory. These changes are already in `sycl` branch (brought in by https://github.com/intel/llvm/pull/19669)
