Add illumos triple
This fixesrust-lang/rust#55553 and adds support for `illumos` as a `target_os` on `x86_64`. In addition to the compile spec and libstd additions, several library dependencies have been bumped in order to permit working builds of cargo and rustup for the new target.
Work originally started by @jasonbking, with subsequent additions by @pfmooney and @jclulow.
Improve rustdoc source code a bit
Very small clean up. I realized that there were too many nested conditions whereas we could just use `and_then`.

Entirely remove `DUMMY_HIR_ID`
Some helpers functions have been introduced to deal with (buggy) cases
where either a `NodeId` or a `DefId` do not have a corresponding `HirId`.
Those cases are tracked in issue #71104.
ptr: introduce len() method on raw slices
It is already possible to extract the pointer part of a raw slice by a
simple cast, but retrieving the length is not possible without relying
on the representation of the raw slice when it is not valid to convert
the raw slice into a slice reference (i.e. the pointer is null or
unaligned).
~Introduce a new function ptr::slice_len() to add this missing feature.~
Introduce a len() method on raw slices to add this missing feature.
fix target & runtool args order
- `TargetTripple::to_string` converts "path triples" to `<target>-<hash>`, but in this case we need the path. Afaict there is no method to get the real triple other than manually matching
- the order of the runtools arguments is inconsistent with the way tests usually pass arguments ie using `runner` key in `.cargo/config`
rustdoc: Don't try to load source files from external crates
Local items defined in external macros shouldn't generate rendered source files and should link to the external crate's docs instead.

improve folder name for persistent doc tests
This fixes#69411, by using the entire path as folder name and storing already visited paths in a HashMap + appending a number to the file name for duplicates.
use is_empty() instead of len comparison (clippy::len_zero)
use if let instead of while let loop that never loops (clippy::never_loop)
remove redundant returns (clippy::needless_return)
remove redundant closures (clippy::redundant_closure)
use if let instead of match and wildcard pattern (clippy::single_match)
don't repeat field names redundantly (clippy::redundant_field_names)
Create output dir in rustdoc markdown render
`rustdoc` command on a standalone markdown document fails because the output directory (which default to `doc/`) is not created, even when specified with the `--output` argument.
This PR adds the creation of the output directory before the file creation to avoid an unexpected error which is unclear.
I am not sure about the returned error code. I did not find a table explaining them. So I simply put the same error code that is returned when `File::create` fails because they are both related to file-system errors.
Resolve#70431
