Add flag enable fp64 emu

[Chao1Han]

This PR is for supporting FP64 emulation, requiring specific compiler and driver IGC versions to be effective.

• The -fsycl-fp64-conv-emu flag ensures that data type conversions to double can be emulated.
• The -cl-poison-unsupported-fp64-kernels flag allows compilation to succeed even when there is double computation.
