Fix createdump 'stack smashing detected' error on arm64

[mikem8361]

The changes from PR #91865 were reverted by PR #95433.

This change restores the fix from PR #91865 by changing the size back to SpecialDiagInfoSize but uses the 4 parameter MemoryRegion constructor that doesn't assert the address/size is on a PAGE_SIZE alignment (PR #95433).

Issue: #108023
