musa: build the docker image and CI container from the MUSA SDK images (#29624)

* musa: build the docker image and CI container from the MUSA SDK images

Use registry.mthreads.com/mcconline/musa_sdk:5.2.0-{devel,runtime}-ubuntu22.04-s5000
instead of registry.mthreads.com/mcconline/inference/pytorch:2.9.1.post1-py3.10-musa5.2.0-mp31-devel-ubuntu22.04-amd64
for the MUSA docker image and the MUSA CI container, and let the runtime stage use the
runtime image instead of reusing the devel one, which drops the MUSA toolchain from the
published images.

* musa: install the MUSA headers and loader path the SDK images omit

musa_sdk:5.2.0-*-s5000 does not ship the cub and thrust headers that the MUSA
backend builds against, and its runtime image does not register
/usr/local/musa/lib with the dynamic loader.

Install both header packages in the build stage and in the MUSA CI container,
and write the loader path in the runtime stage.

* musa: install libmthreads-compute for the MUSA runtime library

The MUSA SDK images do not install libmthreads-compute, which provides
libmusa.so.1 in /usr/lib/x86_64-linux-gnu, so linking anything against the
MUSA backend fails.

* musa: install libmthreads-compute in the runtime stages

The MUSA runtime image does not install libmthreads-compute, so the published
images would have no libmusa.so.1 at run time.
