[SYCL] Pass RewriteTypes=true to the GenXSPIRVWriterAdaptor pass (#3607)

This parameter enables encoding different VC attributes as
OpenCL types, which can be naturally translated from LLVM IR to SPIRV
and vice-versa.
Previously these attributes were transcoded using non-standard
spirv decorations, which are now deprecated and not supported.
