Auto merge of #45366 - ollie27:rustbuild_compiler_docs, r=alexcrichton

rustbuild: Don't try to build rustdoc API docs with compiler docs

rustdoc is built separately to rustc now so the docs would need to be
generated separately as well. Also rustdoc doesn't build at stage 1
which prevented the compiler docs being built at stage 1.

Fixes: #44629
