Matt Arsenault b6b703b2df AMDGPU: Infer no-agpr usage in AMDGPUAttributor (#85948) ...

SIMachineFunctionInfo has a scan  of the function body for inline asm
which may use AGPRs, or callees in SIMachineFunctionInfo. Move this
into the attributor, so it actually works interprocedurally.
    
Could probably avoid most of the test churn if this bothered to avoid
adding this on subtargets without AGPRs. We should also probably
try to delete the MIR scan in usesAGPRs but it seems to be trickier
to eliminate.
