[clang][OpenMP][SPIR-V] Fix addrspace of pointer kernel arguments (#157172)

In SPIR-V, kernel arguments are not allowed to be in the Generic AS, in
both Intel's internal SPIR-V offloading implementation as well as
HIPSPV, `CrossWorkgroup` AS1 is used. Do the same for OMPSPV.

Currently with Generic AS the `llvm-spirv` translator blows up if we are
using it, and if not, the GPU runtime blows up.

To get the existing logic to set the correct AS to kick in, we need to
know if the function is a kernel or not at the time we first create the
function that may end up as the kernel.

I use the existing `arrangeSYCLKernelCallerDeclaration` function to do
the right kernel ABI computation, but since the function is not specific
to SYCL anymore because I merged all the device kernel clang attributes
into one.

Rename the function to be accurate to the current behavior,
`arrangeDeviceKernelCallerDeclaration`.
