Auto merge of #91673 - ChrisDenton:path-absolute, r=Mark-Simulacrum

`std::path::absolute`

Implements #59117 by adding a `std::path::absolute` function that creates an absolute path without reading the filesystem. This is intended to be a drop-in replacement for [`std::fs::canonicalize`](https://doc.rust-lang.org/std/fs/fn.canonicalize.html) in cases where it isn't necessary to resolve symlinks. It can be used on paths that don't exist or where resolving symlinks is unwanted. It can also be used to avoid circumstances where `canonicalize` might otherwise fail.

On Windows this is a wrapper around [`GetFullPathNameW`](https://docs.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-getfullpathnamew). On Unix it partially implements the POSIX [pathname resolution](https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html#tag_04_13) specification, stopping just short of actually resolving symlinks.
