[ROCm] add hipMAGMA support (#51238)
Summary:
Fixes https://github.com/pytorch/pytorch/issues/48831.
- CI image is updated to build hipMAGMA from source and set env MAGMA_HOME.
- CMake is updated to separate different requirements for CUDA versus ROCm MAGMA.
- Some unit tests that become enabled with MAGMA are currently skipped for ROCm due to failures. Fixing these failures will be follow-on work.
