Prior to this commit, `PrimFuncPass` directly removed empty `PrimFunc` objects from the module's `Map<GlobalVar, BaseFunc> functions`. Because it didn't update the `global_var_map_` as well, these two maps could become out of sync. Since the `global_var_map_` is checked as part of `StructuralEqual()`, but isn't displayed when printing to TVMScript, this can result in identical printouts being flagged as non-identical. This commit updates `PrimFuncPass` to call the `IRModuleNode::Remove` method, which updates both the `functions` and `global_var_map_` variables.

PrimFuncPassto call theIRModuleNode::Removemethod, which updates both thefunctionsandglobal_var_map_variables.This is part of changes described in #14486, to improve round-trip failures that occur in lowering.
