Set LocalId parameter of GroupBroadcast to unsigned in SPV-IR (#3084)

LocalId should not be negative. Change its type from signed to unsigned
in SPV-IR aligns with OpenCL work_group_broadcast built-in and use of
GroupBroadcast built-in in SYCL header.

Also change NumElements/Stride parameters of OpGroupAsyncCopy to
unsigned.
