[inductor] Fix AOTInductor output issues (#105773)
Summary: This is a follow-up on https://github.com/pytorch/pytorch/pull/105496. There are several issues with the previous fix,
1) It explicitly does copy for every output at the end of the main function;
2) When an output is ReinterpretView, no as_strided was generated for it;
3) There can be duplicated buffer declarations.
This PR fixes by making sure can_reuse behave consistently between two AOTIndcutor passes, and thus always generate the same set of kernels. It also adds handling of ReinterpretView.
