Auto merge of #43059 - Mark-Simulacrum:rustbuild-2.0, r=alexcrichton

Rework Rustbuild to an eagerly compiling approach This introduces a new dependency on `serde`; I don't believe that's a problem since bootstrap is compiled with nightly/beta always so proc macros are available. Compile times are slightly longer -- about 2-3x (30 seconds vs. 10 seconds). I don't think this is too big a problem, especially since recompiling bootstrap is somewhat rare. I think we can remove the dependency on Serde if necessary, though, so let me know. r? @alexcrichton
