llvmPackages.*: Expose git rev through pkg.src.rev

Also exposes owner, repo, and other attributes available on the original
monorepoSrc. These attributes were previously hidden behind a
runCommand that consumes monorepoSrc and hides this information away.

```
$ nix eval --raw .#llvmPackages_18.llvm.src.rev
llvmorg-18.1.8

$ nix eval --raw .#llvmPackages_git.llvm.src.rev
0e8555d4dbfdfeddc01dc2ecf9a9b6e804f7b645
```
