Rollup merge of #144187 - RalfJung:type-id-base-addr, r=oli-obk

fix handling of base address for TypeId allocations

This fixes the problems discovered by ````@theemathas```` in rust-lang/rust#142789:
- const-eval would sometimes consider TypeId pointers to be null
- the type ID is different in Miri than in regular executions

Both boil down to the same issue: the TypeId "allocation" has a guaranteed 0 base address, but const-eval assumes it was non-zero (like normal allocations) and Miri randomized it (like normal allocations).
