[SYCL][PI][CUDA] Fix transfer stream reuse (#6354)

Fixed a bug that can cause transfer stream to be reused for compute, messing up the synchronization.

[SYCL] Removes more uses of OpenCL header definitions (#6328)

This commit adds various PI definitions and replaces some uses of OpenCL header definitions from the SYCL runtime library.

To further isolate the remaining uses of the OpenCL headers, the includes of cl.h are moved from common.hpp to the dependent files.

Tests updates at: intel/llvm-test-suite#1061

[ESIMD] Implement stateless memory accesses enforcement (#6287)

The driver option -f[no-]sycl-esimd-force-stateless-mem is added.

-fsycl-esimd-force-stateless-mem enables the automatic conversion of stateful memory
accesses via SYCL accessors or surface-index to stateless within ESIMD kernels.
It also disables those ESIMD intrinsics that use stateful accesses that cannot be converted to stateless.
-fsycl-esimd-force-stateless-mem defines the macro __ESIMD_FORCE_STATELESS_MEM
to map the calls of ESIMD API using accessors to calls of API using pointers.
It also passes a switch to sycl-post-link to signal it that it should
ignore the buffer_t attribute and use svmptr_t.

-fno-sycl-esimd-force-stateless-mem is used to tell the compiler not to convert
stateful memory accesses to stateless. Default behavior.

Draft of the design document/proposal for this change-set: #6187

[SYCL][PI][CUDA] Fix too many streams getting synchronized (#6333)

Fixed off-by-one error introduced in https://github.com/intel/llvm/pull/6201 that would cause queue synchronization to synchronize all streams when no stream has been used. The code worked correctly, but this can in some cases impact performance.
