[SYCL] Replace acc with 'fpga' in tests using ONEAPI_DEVICE_SELECTOR (#12551)

As per the ONEAPI_DEVICE_SELECTOR
[documentation](https://github.com/intel/llvm/blob/sycl/sycl/doc/EnvironmentVariables.md#oneapi_device_selector),
the device type can only be cpu, gpu, or fpga (or any combination of
those). Currently, 'acc' is also accepted by ONEAPI_DEVICE_SELECTOR as a
valid device type, which is incorrect.

This PR modifies existing test cases to use 'fpga' instead of 'acc' in
ONEAPI_DEVICE_SELECTOR.
In future, we will completely drop 'acc' from device type in
ONEAPI_DEVICE_SELECTOR.

Partially addresses: #12387
