Convert many files to intra-doc links

Helps with https://github.com/rust-lang/rust/issues/75080
r? @poliorcetics
I recommend reviewing one commit at a time, but the diff is small enough you can do it all at once if you like :)

59a1a05bff Convert many files to intra-doc links 
- Use intra-doc links for `std::io` in `std::fs`
- Use intra-doc links for File::read in unix/ext/fs.rs
- Remove explicit intra-doc links for `true` in `net/addr.rs`
- Use intra-doc links in alloc/src/sync.rs
- Use intra-doc links in src/ascii.rs
- Switch to intra-doc links in alloc/rc.rs
- Use intra-doc links in core/pin.rs
- Use intra-doc links in std/prelude
- Use shorter links in `std/fs.rs`

  `io` is already in scope.

Fix typos in vec try_reserve(_exact) docs 
`try_reserve` and `try_reserve_exact` docs refer to calling `reserve` and `reserve_exact`.
`try_reserve_exact` example uses `try_reserve` method instead of `try_reserve_exact`.

Rollup merge of #76139 - CDirkx:cow-is-borrowed, r=ecstatic-morse 
Make `cow_is_borrowed` methods const

Constify the following methods of `alloc::borrow::Cow`:
 - `is_borrowed`
 - `is_owned`

Analogous to the const methods `is_some` and `is_none` for Option, and `is_ok` and `is_err` for Result.

These methods are still unstable under `cow_is_borrowed`.
Possible because of #49146 (Allow if and match in constants).

Tracking issue: #65143
