Fix spacing of links in inline code.
Similar to #80733, but the focus is different. This PR eliminates all occurrences of pieced-together inline code blocks like [`Box`]`<`[`Option`]`<T>>` and replaces them with good-looking ones (using HTML-syntax), like <code>[Box]<[Option]\<T>></code>. As far as I can tell, I should’ve found all of these in the standard library (regex search with `` r"`\]`|`\[`" ``) \[except for in `core::convert` where I’ve noticed other things in the docs that I want to fix in a separate PR]. In particular, unlike #80733, I’ve added almost no new instance of inline code that’s broken up into multiple links (or some link and some link-free part). I also added tooltips (the stuff in quotes for the markdown link listings) in places that caught my eye, but that’s by no means systematic, just opportunistic.
[Box]: https://doc.rust-lang.org/std/boxed/struct.Box.html "Box"
[`Box`]: https://doc.rust-lang.org/std/boxed/struct.Box.html "Box"
[Option]: https://doc.rust-lang.org/std/option/enum.Option.html "Option"
[`Option`]: https://doc.rust-lang.org/std/option/enum.Option.html "Option"
Context: I got annoyed by repeatedly running into new misformatted inline code while reading the standard library docs. I know that once issue #83997 (and/or related ones) are resolved, these changes become somewhat obsolete, but I fail to notice much progress on that end right now.

Replacing `…std/primitive.reference.html` paths with just `reference`

The discussion seems to have resolved that this lint is a bit "noisy" in
that applying it in all places would result in a reduction in
readability.
A few of the trivial functions (like `Path::new`) are fine to leave
outside of closures.
The general rule seems to be that anything that is obviously an
allocation (`Box`, `Vec`, `vec![]`) should be in a closure, even if it
is a 0-sized allocation.
The (unsafe) Mutex from sys_common had a rather complicated interface.
You were supposed to call init() manually, unless you could guarantee it
was neither moved nor used reentrantly.
Calling `destroy()` was also optional, although it was unclear if 1)
resources might be leaked or not, and 2) if destroy() should only be
called when `init()` was called.
This allowed for a number of interesting (confusing?) different ways to
use this Mutex, all captured in a single type.
In practice, this type was only ever used in two ways:
1. As a static variable. In this case, neither init() nor destroy() are
called. The variable is never moved, and it is never used
reentrantly. It is only ever locked using the LockGuard, never with
raw_lock.
2. As a Boxed variable. In this case, both init() and destroy() are
called, it will be moved and possibly used reentrantly.
No other combinations are used anywhere in `std`.
This change simplifies things by splitting this Mutex type into
two types matching the two use cases: StaticMutex and MovableMutex.
The interface of both new types is now both safer and simpler. The first
one does not call nor expose init/destroy, and the second one calls
those automatically in its new() and Drop functions. Also, the locking
functions of MovableMutex are no longer unsafe.
