How integer truncation heap overflow happens in C++ UEFI ACPI parsing and how to fix it

A high-severity integer truncation vulnerability was discovered in `Mobility.Uefi.Acpi.cpp` where heap allocation sizes were stored in a 16-bit integer (`MO_UINT16`), causing silent truncation when the computed size exceeded 65535 bytes. This led to undersized heap allocations followed by out-of-bounds writes, exploitable by an attacker who can influence ACPI SRAT table contents in virtualized environments. The fix promotes the size variable to `MO_UINTN` (platform-native width) to prevent trunc
