rustc_mir: track inlined callees in SourceScopeData. We now record which MIR scopes are the roots of *other* (inlined) functions's scope trees, which allows us to generate the correct debuginfo in codegen, similar to what LLVM inlining generates. This PR makes the `ui` test `backtrace-debuginfo` pass, if the MIR inliner is turned on by default. Also, `#[track_caller]` is now correct in the face of MIR inlining (cc `@anp).` Fixes #76997. r? `@rust-lang/wg-mir-opt` |

The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
