Rollup merge of rust-lang#46794 - Sh4rK:distribute-intrinsic-natvis, r=estebank

Distribute intrinsic.natvis with the compiler for windows-msvc.

This adds `intrinsic.natvis` to the `windows-msvc` distributions of Rust, enabling the visualization of `str` and slices in the VS debugger. Two other natvis files are already included, this was probably just an oversight.

I also updated `rust-windbg.cmd` to load this file as well.
