  Log Message:
  -----------
  [Driver][SYCL] Add initial SYCL offload compilation support (#107493)

Introduces the SYCL based toolchain and initial toolchain construction
when using the '-fsycl' option. This option will enable SYCL based
offloading, creating a SPIR-V based IR file packaged into the compiled
host object.

This includes early support for creating the host/device object using
the new offloading model. The device object is created using the
spir64-unknown-unknown target triple.

New/Updated Options:
 -fsycl  Enables SYCL offloading for host and device
 -fsycl-device-only
         Enables device only compilation for SYCL
 -fsycl-host-only
         Enables host only compilation for SYCL
