Pull Request Overview
This PR relaxes the assertion condition in the virtual_heap_alloc() function to allow zero alignment values, which represents cases where no specific alignment is requested.
- Modified the assert condition to permit zero alignment as a valid case
- Maintains existing alignment validation for non-zero alignment values

The condition align == 0 may be misleading since zero is not a valid alignment value for memory operations. Consider checking if align is a power of 2 when non-zero, or document that zero specifically means 'no alignment requirement' to clarify the API contract.

I'll proceed as I don't think is worth the back-and-forth we already had in #10324 . If there are updated, I'd add a note about this alignment==0 zero treatmeant, as I still think this is not standard practise (e.g. C++/C compilers will give you an error if you pass a zero alignment attribute).
