This solves #4255

The fix expresses the number of threads per block in size_t in order to avoid an infinite loop for parallel_for ranges greater than INT_MAX.

I believe this issue is also going to affect the HIP plugin:

So we should probably update that as well.

[SYCL][HIP] Fix infinite loop when parallel_for range exceeds INT_MAX

This is the equivalent for HIP of the changes in intel#5095.

It also fixes intel#4255 for the HIP plugin.
