Pre-install GCC 11, 13, 14 (via gcc-toolset) and clang 15, 18 (from S3 tarballs) in the base image so that the setup-linux action only needs to activate the right compiler instead of downloading/installing at runtime. The manylinux_2_28 base image (AlmaLinux 8) ships with GCC 8 as the system default and bundles gcc-toolset-12 under /usr/local/bin. All needed toolset versions are now pre-installed under /opt/rh/gcc-toolset-*. Also register clang runtime library directories with ldconfig so that libclang_rt.asan.so is discoverable by the linker without LD_LIBRARY_PATH workarounds in CI scripts. Authored with Claude.

The logic has been moved to pytorch/test-infra#7879, so here we just need to choose the right compiler. Pull Request resolved: #178361 Approved by: https://github.com/atalman

Pre-install GCC 11, GCC 13, GCC 14, clang 15, and clang 18 in the base image so that the setup-linux action only needs to activate the right compiler instead of downloading/installing at runtime. This reduces CI job latency and removes fragile S3/dnf dependencies from the critical path.
Also register clang runtime library directories with ldconfig so that libclang_rt.asan.so is discoverable by the linker without LD_LIBRARY_PATH workarounds in CI scripts.
