[SYCL] Fix properties include dependency in fpga extensions (#6101)

* [SYCL] Fix include dependency in fpga_lsu.hpp and pipes.hpp

fpga_lsu.hpp/pipes.hpp uses the compile-time properties extension but does not
include the corresponding header file. This issue only shows up when
the fpga extension header (or fpga_lsu.hpp directly) is included before
sycl.hpp. These changes resolve the include dependency.
