Use disabler() for optional dependencies.
Extract repeated build type checks into is_debug/is_release variables.
Consolidate compiler flags into single add_project_arguments() calls.
Simplify dependency list building (Meson auto-ignores disabled deps).
Streamline platform checks using 'in' operator.
Remove redundant variables (xscrnsaver_found, gtk_version, config_h_inc).
Simplify ncurses and header detection with clearer fallback chains.
Consolidate install_data() calls for files in same directory.
For meson we dont just check for the presence of a dependency and
then auto enable it.
Users must enable features explicit. This helps with having
deterministic results.
Also remove the general `plugins` switch which was used to
enable/disable both python and c plugins. Users can just use
those switches.
In out autotools build we check for all kinds of curses and their
support for wide character.
Let's focus on more modern systems until someone complains.
For autotools this was added in:

Regarding:
https://github.com/profanity-im/profanity/issues/1334
I think libstrophe is rather common now and should be treated
like all the other dependencies anyways.
So I'll remove this from the meson files at least. Since my
goal is to have a cleaner build system.
In autotools we had `package_status` which we set to either
`release` or `development`.
When converting from autotools to meson we used that mechanism
as well. But actually meson has a default way of handling this
with the option `buildtype`.
The following values are possible:
debug, debugoptimized, release, plain
So our `package_status = development` will now be
`if get_option('buildtype') == 'debug' or get_option('buildtype') ==
'debugoptimized'`. Probably we could also use
`if get_option('buildtype') == 'release'. But like this the
`plain` will be really plain.
Usage:
```
meson setup build --buildtype=debug
meson compile -C build
```
