framework laptop 16 hybrid gpu support

[lamikr]

I received a Framework 16 laptop for testing and development with AMD's cpus and gpus.

• 7840HS CPU
• 780M iGPU (gfx1103) with 12 CU's (rocm-smi device id 0x7480)
• 7700S GPU (gfx1102) with 32 CU's (rocm-smi device id 0x15bf
• 32GB so-ram (need to check if I can update it to 64 or 96 gb later)

So far tested:

• gfx1102 7700S works with basic tests ok. Have not had time to do any benchmarks yet with it.
• gfx1103 will need more work and will start debugging it now

This is the first time I am able to test with hyprid gpu's and would like to find ways to test all 3 scenarios:

• Either 7700S or 780M alone (should be doable by masking another gpu away from rocm)
• Some tasks where it would make sense to share the task between both GPU's
