refactor(allocator): disable fixed size allocators on unsupported platforms

[overlookmotel]

Do not compile code for fixed-sized allocators (for raw transfer) on unsupported systems (32 bit, or big-endian).

This allows removing the workaround to prevent compilation failure on 32-bit systems due to 1 << 32 overflowing usize. This code is no longer compiled on 32-bit systems.
