* `IRModule.clone`: Clone the module. While in C++, a module can be copied using `IRModule::CopyOnWrite()`, copying a module in Python required passing all members into the `IRModule` initializer. The `IRModule.clone` method provides an easier way to copy an `IRModule` from python. * `IRModule.__delitem__`: Remove a function from the module. This exposes the C++ method `IRModuleNode::Remove` for use in the python API. This uses the python `del` keyword, similar to a native python list. Similar to the existing `IRModule.__getitem__`, this can be called with either a `GlobalVar` or a python string. * `IRModule.__contains__`: Check if a function is in the module. This allows the pythone keyword `in` to check if a module contains a specific function. Similar to the existing `IRModule.__getitem__`, this can be called either with a `GlobalVar` (`if gvar in mod`) or with a python string (`if "function_name" in mod`).

Prior to this commit, `relax.transform.RunCodegen` required a list of entry functions for a module, defaulting to `"main"` if not specified. The list of entry functions is duplicate information that could be inferred from the module, and should not be required from the user. This commit updates `RunCodegen` to treat all externally-exposed functions as entry points, in the same manner as `DeadCodeElimination`. For backwards compatibility, the `entry_functions` argument is still accepted, and is used to augment the list of externally-exposed functions.
