this looks fine, but I'll be surprised if it continues to get rid of the warning |

Summary:
To support embedded system builds which threw an error on the warning for left shift by 32 on a 32 bit dtype, the code was modified to:
```
memory_offset |= static_cast<size_t>(memory_offset_high)
<< (sizeof(size_t) - sizeof(uint32_t));
```
This fails for build of OSS qwen example however.
Instead, we modify to add a check for
```
sizeof(size_t) > sizeof(uint32_t)
```
in the conditional instead of changing the computation.
In our builds of interest, this compiles away the if branch
