Remove unneeded handling for `ExternalLocation::Unknown` in rustdoc render context
Should fix perf regression introduced in https://github.com/rust-lang/rust/pull/113623.

Add jump to doc
I'm using the source code pages of the compiler quite a lot, but one thing missing is the possibility to jump back from the source code to the item documentation. Since I also got a few others complaining about it, I think it's fine to add it since this option is nightly only.
This PR adds a link to jump back to item's documentation on the item definition (so on `Bar` in `struct Bar {... }`, as described in the unofficial [RFC](https://github.com/GuillaumeGomez/rfcs/blob/rustdoc-jump-to-definition/text/000-rustdoc-jump-to-definition.md)).

Fix union fields display

So two bugs in this screenshot: no whitespace between field name and type name, both fields are on the same line. Both problems come from issues in the templates because all whitespace are removed if a askama "command" follows.

Remove unneeded `Buffer` allocations when `&mut fmt::Write` can be used directly
With the recent changes, `wrap_item` can now directly take `&mut Write`, which makes some `Buffer` creations unneeded.

Migrate `item_foreign_type` to Askama
This PR continues the migration of `print_item.rs` functions to Askama. This piece of work migrates the function `item_foreign_type`

Clean up usage of `cx.tcx` when `tcx` is already set into a variable
I discovered a few cases where `cx.tcx` (and equivalents) was used whereas `tcx` was already stored into a variable. In those cases, better to just use `tcx` directly.

Migrate `item_static` to Askama
This pull request addresses the type signature of the item_static function in our codebase. Previously, this function accepted a mutable reference to a Buffer for writing output. The current changes modify this to instead accept a mutable reference to any type that implements the Write trait.

Introduce `AliasKind::Inherent` for inherent associated types
Allows us to check (possibly generic) inherent associated types for well-formedness.
Type inference now also works properly.

rustdoc-search: add slices and arrays to index
This indexes them as primitives with generics, so `slice<u32>` is how you search for `[u32]`, and `array<u32>` for `[u32; 1]`. A future commit will desugar the square bracket syntax to search both arrays and slices at once.
