Rollup merge of #97511 - jyn514:faster-cargo-build, r=Mark-Simulacrum 

Don't build the compiler before building rust-demangler

This saves a lot of time compiling, since rust-demangler doesn't actually use any unstable features.

This is not quite ideal because it uses ToolStd, not ToolBootstrap, so rust-demangler would be able to add unstable library features in the future. But it's a lot better than before, and `builder.cargo` doesn't currently know how to handle stages other than 0.
