  [Offload][AMDGPU] Fix RPC server on mixed w32 w64 workloads (#185496)

Summary:
This was a regression from the original LLVM-gpu-loader. We used to
handle `-mwavefrontsize64` correctly in the loader by over-allocating
memory and just leaving the upper 32-bits masked off. In order to handle
this in offload we need to scan loaded kernels to see how much memory we
need to allocate. This should be safe, the protocol is designed to
handle an arbitrary size and worst-case this just wastes space.
