RawVec was previously exposed for compiler-internal use (libarena specifically) in 1acbb0a

Since it is unstable, doc-hidden and has no associated tracking issue it was never meant for public use. And since
it is no longer used outside alloc itself it can be made private again.

Also remove some functions that are dead due to lack of internal users.

This helps with (but does not fix)
rust-lang#84738. I tested on
jyn514/objr@edcee7b
and still hit ICEs.

This *continues* to cause regressions. This code will be unnecessary
once access to the resolver happens fully before creating the tyctxt
(rust-lang#83761), so load all crates unconditionally for now.

Before, you could have the confusing situation where the command to
generate a component had no relation to the name of that component (e.g.
the `rustc` component was generated with `src/librustc`). This changes
the name to make them match up.

rustdoc: Go back to loading all external crates unconditionally

This *continues* to cause regressions. This code will be unnecessary
once access to the resolver happens fully before creating the tyctxt
(rust-lang#83761), so load all crates unconditionally for now. To minimize churn, this leaves in the code for loading crates selectively.

"Fixes" rust-lang#84738. Previously: rust-lang#83738, rust-lang#85749, rust-lang#88215

r? `@petrochenkov` cc `@camelid` (this should fix the "index out of bounds" error you had while looking up `crate_name`).

Change paths for `dist` command to match the components they generate
