yauto: Handle PKG_CHECK_MODULES that define multiple modules (#5075)

**Summary**

The PKG_CHECK_MODULES macro in configure.ac files can define more than
one module (see
[here](https://autotools.info/pkgconfig/pkg_check_modules.html)).
Previously all the entries were simply added into the same
`pkgconfig()`.
This properly separates them into their own entries and also accepts
"<=" and "=" comparators (though these aren't used for anything except
detecting version definitions)

Also fix adding dependencies for combined configure.ac/Python projects

Old behaviour:
```
 go-task new -- gammastep https://gitlab.com/chinstrap/gammastep/-/archive/v2.0.9/gammastep-v2.0.9.tar.bz2
[...]
 yq '.builddeps' packages/g/gammastep/package.yml
- pkgconfig(libdrm)
- pkgconfig(x11)
- pkgconfig(xxf86vm)
- pkgconfig(xcb)
- pkgconfig(xcb-randr)
- pkgconfig(wayland-client wayland-scanner)
- pkgconfig(glib-2.0 gobject-2.0)
- pkgconfig(glib-2.0 gio-2.0)
```

New behaviour:
```
 go-task new -- gammastep https://gitlab.com/chinstrap/gammastep/-/archive/v2.0.9/gammastep-v2.0.9.tar.bz2
[...]
 yq '.builddeps' packages/g/gammastep/package.yml 
- pkgconfig(libdrm)
- pkgconfig(x11)
- pkgconfig(xxf86vm)
- pkgconfig(xcb)
- pkgconfig(xcb-randr)
- pkgconfig(wayland-client)
- pkgconfig(wayland-scanner)
- pkgconfig(glib-2.0)
- pkgconfig(gobject-2.0)
- pkgconfig(gio-2.0)
```


**Test Plan**

- `go-task new -- gammastep
https://gitlab.com/chinstrap/gammastep/-/archive/v2.0.9/gammastep-v2.0.9.tar.bz2`
produces correct build dependencies
- `go-task new -- rapidyml
https://github.com/biojppm/rapidyaml/archive/refs/tags/v0.7.2.tar.gz`
still works correctly
- `go-task new -- pip-tools
1ef453f10f/pip-tools-7.4.1.tar.gz`
still works correctly

**Checklist**

- [x] Package was built and tested against unstable
- [ ] This change could gainfully be listed in the weekly sync notes
once merged <!-- Write an appropriate message in the Summary section,
then add the "Topic: Sync Notes" label -->
