Based on #1242, I don't think this is required but it does remove that
issue and checking on compiler explore it does simplify the generated
code.

The extra will will enable additions of some new validators and reduce

generating a seg fault if no default and no config file provided.
Fixes#1197
This was likely introduced by the combination of fixes for some issues
with the config parsing and some updates to the as<T> method a while
back. This edge case on the handling of the config pointer with as was
not overlooked in the earlier testing.

The default formatter has hardcoded ratio at which the long options are
aligned. It's currently 1/3 of the column, which makes the default look
awkward:
```
-h, --help Print
--option Something
```
A ->long_option_alignment_ratio(6/30.f) allows output to look like this:
```
-h, --help Print
--option Something
```
The 1/3 ratio is also bad if you want to print "descriptive" long
options on a single line, because then you might want to increase the
column width, but that means you waste more space on short options.
e.g. ->column_width(46)
```
-l, --very-descriptive-long-option Something
```
vs. ->column_width(38)
```
-l, --very-descriptive-long-option
Something
```
vs. ->column_width(38) ->long_option_alignment_ratio(6/38.f)
```
-l, --very-descriptive-long-option Something
```
Any absolute offset `X` can be set as `X/column_width`, so provide a
ratio-based interface.
I would have prefered to give an absolute integer offset, but we still
have to preserve the functionality that does 1/3 if user changed
nothing, which means that ratio-based interface is simpler.
I don't have a good idea for the name, "short_option_ratio" might work
as well.
The setter does not sanity check that the value is in [0;1] range.

Previously the callbacks were done first, but with custom callbacks this
cause side effects unexpectedly.

I am starting to use CLI11 in a project and I came across an
inconvenience in code like this
```c++
const std::string description(std::format("description"));
app.add_flag("--flag", description);
```
As far as I can tell. I cannot directly use the description here. The
reason seems to be to distinguish between assignment and description. So
only `const std::string` or `const char*` and so on can be used here.
But a `const std::string &&` can not be used.
With the changes in the PR the code can also be written like this:
```c++
app.add_flag("--flag", std::format("description"));
```
The `add_flag` function can then be used with a const string or an
rvalue reference to a string.
A bit OT: I was a bit confused by this part of the existing comment ` if
a variable string is passed that variable will be assigned the results
from the flag` I think this might be wrong, but I am not sure.
