Reland: [TensorExpr] Add `CodeGen::call_raw` method. (#57551)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/57551
The new method allows to pass input and output arguments by `void*`
pointers instead of CallArgs. That helps to reduce the invocation
overhead. Currently this is only supported in LLVM codegen.
Relanding #55113 (the entire stack) which was reverted because I forgot
to guard a new test with `ifdef LLVM`.
Test Plan: Imported from OSS
