make it more clear what 'Tier 2' (without host tools) means
When saying that Rust "builds official binary releases for each tier 2 target", it's not at all clear that this does not mean we build a compiler and cargo for that target.
[rustdoc] Fix type based search
Fixes https://github.com/rust-lang/rust/issues/114522.
The problem was a bit more tricky than I originally thought it would be: we only kept type ID and generics in short, but as soon as there was a full path in the user query, the element didn't get an ID anymore because the ID map didn't know about `x::y` (although it knew about `y`). So for this first problem, I instead always pass the element name to get the ID.
Then a new problem occurred: we actually needed to check if paths matched, otherwise whatever the path, as long as the "end types" match, it's all good. meaning, we needed to add path information, but to do so, we needed it to be added into the search index directly as there was no mapping between `"p"` and `"q"`.
I hope this explanation makes sense to someone else than me. ^^'

Skip rendering metadata strings from include_str!/include_bytes!
The const rendering code in rustdoc completely ignores consts from expansions, but the compiler was rendering all consts. So some consts (namely those from `include_bytes!`) were rendered then ignored.
Most of the diff here is from moving `print_const_expr` from rustdoc into `rustc_hir_pretty` so that it can be used in rustdoc and when building rmeta files.
avoid stdout redirection on `curl` executions
Avoid redirecting the curl output directly to the stdout. This alteration affects the integrity of the file during the retry process, as it also redirects the logs from the retries. Consequently, this leads to the bootstrap process failing because of an invalid checksum.
