[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.

[SYCL] Add aspect for bfloat16 (#5720)

This PR adds a new aspect ext_oneapi_bfloat16 to allow a runtime check for if the device supports the bfloat16 floating point type.
Only the CUDA implementation for checking if the device supports this aspect is added.

Updated test: intel/llvm-test-suite#888

[SYCL][Doc] Initial draft of root-group proposal (#6163)

Introduces a new group type (root_group) representing all work-items
executing a kernel, along with an associated kernel property that
enables all work-items within a root_group to synchronize.
