feat: enable notationItem in "mixfix" notation commands (#10378) 
This PR enables using `notation` items in
`infix`/`infixl`/`infixr`/`prefix`/`postfix`. The motivation for this is
to enable being able to use `pp.unicode`-aware parsers. A followup PR
can combine core parsers as such:
```lean
infixr:30 unicode(" ∨ ", " \\/ ") => Or
```

Continuation of #10373.

feat: add unicode(...) parser syntax and pp.unicode option (#10373) 
This PR adds a `pp.unicode` option and a `unicode("→", "->")` syntax
description alias for the lower-level `unicodeSymbol "→" "->"` parser.
The syntax is added to the `notation` command as well. When `pp.unicode`
is true (the default) then the first form is used when pretty printing,
and otherwise the second ASCII form is used. A variant, `unicode("→",
"->", preserveForPP)` causes the `->` form to be preferred; delaborators
can insert `→` directly into the syntax, which will be pretty printed
as-is; this allows notations like `fun` to use custom options such as
`pp.unicode.fun` to opt into the unicode form when pretty printing.

Additionally:
- Adds more documentation for the `symbol` and `nonReservedSymbol`
parser descriptions.
- Adds documentation for the
`infix`/`infixr`/`infixl`/`prefix`/`postfix` commands.
- The parenthesizers for symbols are improved to backtrack if the atom
doesn't match.
- Fixes a bug where `&"..."` symbols aren't validated.

This is partial progress for issue #1056. What remains is enabling
`unicode(...)` for mixfix commands and then making use of it for core
notation.

chore: upstream Std.Util.ExtendedBinders (#3320) 
This is not a complete upstreaming of that file (it also supports `∀ᵉ (x
< 2) (y < 3), p x y` as shorthand for `∀ x < 2, ∀ y < 3, p x y`, but I
don't think we need this; it is used in Mathlib).

Syntaxes still need to be made built-in.
