Simplify Argument exposition-only constructors
Although they are public, they are not meant for end-users
to use, so we can change its interface to use less sfinae.

Determine negative numeric values with a grammar
Two differences that diverge from the existing behavior:

  1. Leading zeros are not allowed for integers.  Negative
     octal numbers such as `-066` are not meant to be treated
     as positional arguments, but existing code recognize them
     as decimal numbers.  Note that negative floating-point
     numbers with leading zeros (`-003.`) are unambiguous and
     are recognized.
  2. Inf and NaN are not recognized.  This is because options
     like `-inf` is indistinguishable from a compound argument
     that meant to be a shorthand for `-i -n -f`.

Default --help to print help and exit
The change also fixes a rare bug introduced in 9007958:
when there are duplicated keys, insert_or_update overrides
previously inserted ones, emplace doesn't.

Support capturing remaining() arguments
This kind of argument works as if having the "remaining" nargs,
inspired by Python's `argparse.REMAINDER`.

This change also reduces the size of `Argument` by 8 bytes.

Fix various issues in Argument constructor
Before this change:

1. When the input is built-in string literal or cv-`char*`,
   `is_optional` constructs temporary `std::string` while
   `mNames` initializer is also constructing `std::string`
   due to the use of `std::initializer_list`.
2. When the input is `std::string_view`, doesn't compile.
3. When the input is `std::string`, `mNames` initializer
   moves `args`.  If argument name is longer than
   `std::string`'s SSO buffer, bad thing will happen because
   `is_optional` will be accessing `args` in moved-from
   states.

Because of the use of `strtol` which expects nul-terminated
input, `is_*` series functions must take `std::string`.  This
restriction may be removed after AppleClang adds `<charconv>`.
But for now, it complicates the patch.  My solution is to
create an array prvalue still, but use a array reference
rather than `std::initializer_list` to refer to it, so that
the code in delegated constructor can keep using fold
expressions after the necessary `std::string` objects being
created.
