Split iree-libs into iree-compiler + fusilli-libs stages for multi-arch CI

The iree-compiler stage (~3hr LLVM build) runs parallel to math-libs,
then fusilli-libs runs after both complete. This avoids blocking the
IREE compiler build on math-libs while still satisfying fusilliprovider's
hipdnn dependency.

Changes:
- BUILD_TOPOLOGY.toml: Split iree-libs stage/group into iree-compiler
  and fusilli-libs, with feature_group="IREE_LIBS" to preserve single toggle
- multi_arch_build_portable_linux.yml: Add iree-compiler and fusilli-libs jobs
- CMakeLists.txt: Remove resolved TODO, fix quoting, enable by default

Resolves: #3451
