  [OpenMP] Make generating offloading entries more generic

This patch moves the logic for generating the offloading entries to the
OpenMPIRBuilder. This makes it easier to re-use in other places, such as
for OpenMP support in Flang or using the same method for generating
offloading entires for other languages like Cuda.

  [OpenMP] Make clang argument handling for the new driver more generic

In preparation for accepting other offloading kinds with the new driver,
this patch makes the way we handle offloading actions more generic. A
new field to get the associated device action's toolchain is used rather
than manually iterating a list. This makes building the arguments easier
and makes sure that we doin't rely on any implicit ordering.

  [Clang] Make enabling the new driver more generic

In preparation for allowing other offloading kinds to use the new driver
a new opt-in flag `-foffload-new-driver` is added. This is distinct from
the existing `-fopenmp-new-driver` because OpenMP will soon use the new
driver by default while the others should not.

  -----------
  [CUDA] Add driver support for compiling CUDA with the new driver

This patch adds the basic support for the clang driver to compile and link CUDA
using the new offloading driver. This requires handling the CUDA offloading kind
and embedding the generated files into the host. This will allow us to link
OpenMP code with CUDA code in the linker wrapper. More support will be required
to create functional CUDA / HIP binaries using this method.
