Changed all references from hipSYCL to AdaptiveCpp

[lrpablo]

Description

All references to hipSYCL have been changed to AdaptiveCpp. Most of the targets failed to compile because they are trying to compile using the -fsycl flag. The only target that compiles is the rng target for CPU; on GPU, it also generates the -fsycl error.
