Maksim Levental 6a4f66476f [MLIR][Python] restore liveModuleMap (#158506 )

There are cases where the same module can have multiple references (via
`PyModule::forModule` via `PyModule::createFromCapsule`) and thus when
`PyModule`s get gc'd `mlirModuleDestroy` can get called multiple times
for the same actual underlying `mlir::Module` (i.e., double free). So we
do actually need a "liveness map" for modules.

Note, if `type_caster<MlirModule>::from_cpp` weren't a thing we could guarantree
this never happened except explicitly when users called `PyModule::createFromCapsule`.
