5f619dc95a [v0.30] Add support for XCDs and matrix cores
For XCDs, we dont show them if the GPU is made of a single
XCD, as it adds little value

For matrix cores, we assume it can be computed as
compute_units * simds_per_cu, it seems to work for the GPUs
I checked from CDNA3 and RDNA3. Not sure what would happen for
older GPUs that do not have matrix cores though.

98bb02e203 [v0.30] Allow users to select backend from build script
Before we had AMD support, CMakeLists.txt tried to enable all backends
by default. Now that we have AMD support, that does not make that much
sense so instead it will only enable the backend specified by the user
(with the -DENABLE_XXX_BACKEND flags)

Then, before AMD support, the build.sh script was useful to just
invoke cmake and let it figure out the backends, but the script was
a bit useless after the mentioned change in the CMakeLists.txt.

Therefore, this commit allow users to specify an argument, like:

./build.sh cuda

To specify what backend/s to enable, without the need to manually
configure the build with the -DENABLE_XXX_BACKEND flag. Note that
multiple backends are also allowed, like:

./build.sh intel,hsa

Would enable both Intel and HSA backends (which could make sense for
example in a system with Intel iGPU an an AMD dGPU).

78d34e71f1 [v0.30][AMD] Add support to fetch bus width, global memory and LDS size
We can use hsa_amd_agent_iterate_memory_pools to fetch info about GPU
memory pools in the GPU. HSA_AMD_SEGMENT_GROUP seems to be LDS, and
HSA_AMD_SEGMENT_GLOBAL seems to be global memory.

However, the latter is reported multiple times (I don't know why). The
only solution I found for this is to check for the
HSA_AMD_MEMORY_POOL_GLOBAL_FLAG_EXTENDED_SCOPE_FINE_GRAINED flag, which
seems to be reported only once.

For bus width, we simply use HSA_AMD_AGENT_INFO_MEMORY_WIDTH.
