- Bump meson version to 1.3
- Bump default cpp_std (required by Catch2 3.x, still possible for c++11
fallback)
- Move option `single-file-header` and `precompiled` to `mode`
- Make pkgconfig optional
- Refactor tests, fix a bizzare situation where filename contains quote
or escape characters
Rework some of the validator locations, add documentation, and fix some
lingering issues with validators.
The extra will will enable additions of some new validators and reduce
compile times for those that are not needed.

**Short description**
Application fails with `CLI::ConversionError` in some locales if the
application locale is set.
**Root cause**
CLI11 uses `std::stringstream` to format default value and
`strtol`/`strtod` to parse them back. The first method adds
locale-specific thousand separators but the second method parses the
number only up to the first separator. This causes an exception when the
same value is converted to string representation and then parsed back.
Examples: in _en_US_ locale 1234.56 is "1,234.56" and in de_DE locale
1234.56 is "1.234,56".
**Reproduction**
```c++
#include <string>
#include <CLI/CLI.hpp>
int main(int argc, const char **argv)
{
std::locale::global(std::locale(""));
CLI::App app{"Bug report app"};
long foo;
app.add_option("FOO", foo, "Foo option")
->envname("FOO")
->default_val(1234567);
CLI11_PARSE(app, argc, argv);
return 0;
}
```
Output:
```
$ g++ -Wall -Wextra -I CLI11/include/ cli11-bug-locale-string.cpp -o cli11-bug-locale-string
$ for locale in C en_US de_DE fr_FR de_CH; do echo "locale $locale"; LC_NUMERIC=$locale.UTF-8 ./cli11-bug-locale-string && echo OK; echo; done
locale C
OK

locale de_CH

```
**Fix description**
The fix strips group separators from the input string. This extends a
bit the logic introduced in change #968 for `_` and `'` separators.
There are no unit tests for the change because it requires to have all
mentioned locales to be installed in the system.

This is follow up work to my previous series. I've tried to make the
Meson build mirror the CMake build more closely. I've also made an
attempt at adding some instructions to the documents on using Meson.

This series cleans up and modernizes the Meson code a bit:
- It adds the license SPDX name to the proper field
- Sets a minimum version, the version is fairly old, but without setting
a version then Meson will never warn about issues, including potentially
important ones like "this happens to work in some cases but wasn't
intended and doesn't work in all cases"
- uses more modern Meson features to make things easier for consumers
- Fixes the tests using the ensure_utf8 helpers by ensuring that they're
actually built, and placing them in the correct path.
- Adds the Meson test to the CI
Fixes#845 as discussed.
Comparing the two approaches of getting `argv`:
1. The "old" way, through `CLI::argv()`:
✔️ Works automatically and almost everywhere
❌ Small abstraction overhead on macOS
❌ Does not work in weird edge-cases such as missing `/proc`
2. This PR, through `app.ensure_utf8`:
✔️ True zero-overhead abstraction: you don't pay for what you don't use
✔️ Less moving parts than the "old" approach, probably can't be broken
❌ Requires extra code to be written by the user (which is sad because
ideally everyone should use this by default)

* meson: add support for testsuite
* meson: fix deprecation warning for run_command with unchecked return code
This would implicitly default to false, so if something bizarre happened
and the command errored out, meson would consider that fine. Now meson
emits a warning about this deprecated legacy behavior, suggests that it
will eventually change, and, most importantly, prevents a warning-free
build.
Suppress the warning by manually specifying the sensible behavior, which
is to fail on errors.
* meson: download catch2 on demand if a system version is unavailable
Produced by running `meson wrap install catch2` and checking the results
into git.
No modifications to the build files are expected; this makes use of
