Related to #7433
This extracts our "launched from desktop" logic into a config option.
The default value is detection using the same logic as before, but now
this can be overridden by the user.
This also adds the systemd and dbus activation sources from #7433.
There are a number of reasons why we decided to do this:
1. It automatically gets us caching since the configuration is only
loaded once (per reload, a rare occurrence).
2. It allows us to override the logic when testing. Previously, we
had to do more complex environment faking to get the same
behavior.
3. It forces exhaustive switches in any desktop handling code, which
will make it easier to ensure valid behaviors if we introduce new
launch sources (as we are in #7433).
4. It lowers code complexity since callsites don't need to have N
`launchedFromX()` checks and can use a single value.
Sets the LANGUAGE environment variable based on the preferred languages
as reported by NSLocale.
macOS has a concept of preferred languages separate from the system
locale. The set of preferred languages is a list in priority order
of what translations the user prefers. A user can have, for example,
"fr_FR" as their locale but "en" as their preferred language. This would
mean that they want to use French units, date formats, etc. but they
prefer English translations.
gettext uses the LANGUAGE environment variable to override only
translations and a priority order can be specified by separating
the languages with colons. For example, "en:fr" would mean that
English translations are preferred but if they are not available
then French translations should be used.
To further complicate things, Apple reports the languages in BCP-47
format which is not compatible with gettext's POSIX locale format so
we have to canonicalize them. To canonicalize the languages we use
an internal function from libintl. This isn't normally available but
since we compile from source on macOS we can use it. This isn't
necessary for other platforms.
`WINDOWID` is the conventional environment variable for scripts that
want to know the X11 window ID of the terminal, so that it may call
tools like `xprop` or `xdotool`. We already know the window ID for
window protocol handling, so we might as well throw this in for
convenience.

This fixes two issues. In fixing one issue, the other became apparent so
I fixed both in this one commit.
The first issue is that on macOS, the `open` command should take the
`-t` flag to open text files in a text editor. To do this, the `os.open`
function now takes a type hint that is used to better do the right
thing.
Second, the order of the paths that we attempt to open when editing a
config on macOS is wrong. Our priority when loading configs is well documented:
https://ghostty.org/docs/config#macos-specific-path-(macos-only). But
open_config does the opposite. This makes it too easy for people to have
configs that are being overridden without them realizing it.
This commit changes the order of the paths to match the documented
order. If neither path exists, we prefer AppSupport.
Fixes#2432
On macOS, processes with an NSApplicationMain entrypoint do not have
access to libc argc/argv. Instead, we must use NSProcessInfo. This
commit introduces an args iterator that uses NSProcessInfo, giving us
access to the args.
This also fixes an issue where we were not properly skipping argv0 when
iterating over the args. This happened to be fine because we happened to
ignore invalid args but it introduces a config error.
