[NFC][SYCL] Move FPGA AOT test to the sycl project, as it does a full compile (#4249)

The driver area should be used for specific driver testing. The
return code test has dependencies on additional files related to
a full compile, so move this to the sycl area.

clang/test/Driver/Inputs/SYCL/aoc renamed to sycl/test/fpga_tests/Inputs/aoc
