rocALUTION 3.2.1 for ROCm 6.3.0

Added

• Support for gfx1200, gfx1201, and gfx1151.

Changed

• Changed the default compiler from hipcc to amdclang in the installation script and cmake files.
• Changed the address sanitizer build targets. Now only gfx908:xnack+, gfx90a:xnack+, gfx940:xnack+, gfx941:xnack+, and gfx942:xnack+ are built with BUILD_ADDRESS_SANITIZER=ON.

Resolved issues

• Fix hang in RS-AMG for Navi on some specific matrix sparsity patterns.
• Fix wrong results in Apply on multi-GPU setups.
