eda0ca54c1 fix(parser): Simplify the common getter API
Clap has focused on reporting development errors through assertions
rather than mixing user errors with development errors.  Sometimes,
developers need to handle things more flexibly so included in #3732 was
the reporting of value accessor failures as internal errors with a
distinct type.  I've been going back and forth on whether the extra
error pessimises the usability in the common case vs dealing with the
proliferation of different function combinations.  In working on
deprecating the `value_of` functions, I decided that it was going to be
worth duplicating so long as we can keep the documentation focused.

db863de6c1 docs(examples): Show how to do default subcommands
While we don't have a built-in mechanism, its relatively easy to support
with the APIs we provide.

Inspired by #3566

272f840178 feat: Replace core set of AppSettings with functions
This is a part of #2717

Some settings didn't get getters because
- They are transient parse settings (e.g. ignore errors)
- They get propagated to args and should be checked there

`is_allow_hyphen_values_set` is a curious case.  In some cases, we only
check the app and not an arg.  This seems suspicious.

befee6667b docs: Re-work examples
This creates distinct tutorial examples from complex feature examples
(more how-tos).  Both sets are getting builder / derive versions (at
least the critical ones).
