Rollup merge of #73715 - MaulingMonkey:pr-natvis-tuples, r=Amanieu

Browse source 
debuginfo:  Mangle tuples to be natvis friendly, typedef basic types

These changes are meant to unblock rust-lang/rust#70052 "Update hashbrown to 0.8.0" by allowing the use of `tuple<u64, u64>` as a .natvis expression in MSVC style debuggers (MSVC, WinDbg, CDB, etc.)

* f8eb81b does the actual mangling of `(u64, u64)` -> `tuple<u64, 64>`
* 24a728a allows `u64` to resolve (fixing `$T1` / `$T2` when used to visualize `HashMap<u64, u64, ...>`)
