  -----------
  [AMDGPU] Fix backward compatibility kernarg preload prolog base offset (#201355)

Backward compatibility preload prolog loaded args from kernarg-segment
byte 0, but on non-AMDHSA triples the explicit args start at
`getExplicitKernelArgOffset()` (value: 36), so preloaded SGPRs held the
runtime header instead of the arguments
