fix handling of base address for TypeId allocations This fixes the problems discovered by ````@theemathas```` in https://github.com/rust-lang/rust/pull/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). r? ````@oli-obk````
