686b0379ce feat(multicall): Stablize multicall 
`multicall` allows you to have one binary expose itself as multiple
programs, like busybox does.  This also works well for user clap for
parsing REPLs.

Fixes #2861

1a2b7acd60 test(multicall): Conditionalize suggestion-related case 
This impacts the error code (#3676) and the error body and without
suggestions, its redundant.

0628d04174 perf(derive): Reuse allocations for external subcommands 
In case the `ArgMatches` is cloned, this forces a constraint that the
underlying type impls `Clone` but that should be safe as we only support
`String` and `OsString`.

5806e16dd4 refactor(derive): Don't alias arg matches 
Right now, the aliasing is safe (the compiler says so!) but we're going
to be switching to a `&mut` and need to ensure we don't alias.

4a733cd879 fix: Bump MSRV to 1.56.0 
This is needed for `Bound::cloned` and fits within official MSRV policy
(2 versions back) and unofficial (6 months, see #3267)

63aa236141 feat(parser): Convenient range value parsers 
There are several approaches with this
- `value_parser(N..M)`: creates an i64 range
- `value_parser(value_parser!(u16).range(10..))`: creates an u16 range
  that starts at 10
- `RangeI64ValueParser`: create whatever range you want

I was hoping to generalize `RangeI64ValueParser` for any source type,
not just i64, but ran into issues and decided to punt.  I chose `i64` as
the source type as it seemed the most general and didn't run into
portability issues like `isize`.

This is a step towards #3199.  All that is left is for the derive to use
this.

bdf9d841ef doc(parser): Expand examples for ValueParser 
This identified a problem with the blanket implementations for
`TypedValueParser`: it only worked on function pointer types and not unnamed
function tupes.  The user has to explicitly decay the function type to a
function pointer to opt-in, so I changed the blanket impl.  The loss of
the `OsStr` impl shouldn't be too bad.
