Twin mr of [plasma-workspace!2232](plasma-workspace!2232) for the binary and fuzzy clock widgets.

- match offset names only exactly, so 'time utc' wouldn't show 'UTC-10:00'
- show only city names (without continent) so relevance ranking works more accurately
- change delimiter for zones with country and comment for less ambiguity
- use QLatin1String instead of QString for composite names

In case of conflict in i18n, keep the version of the branch "ours"

There are different kinds of Islamic calendars, and Qt only supports
"Islamic calendar, tabular". This adds support for another two Islamic
calendars.

The Islamic religious calendar and Saudi Arabia's Umm al-Qura
calendar, however, are based on the observation of the crescent moon.
It is thus affected by the position at which the observations are
made, seasonal variations in the time of sunset, the eccentricities of
the moon's orbit, and even the weather at the observation site. This
makes it impossible to calculate in advance, and it causes the start
of a month in the religious calendar to differ from the civil calendar
by up to three days.

Using astronomical calculations for the position of the sun and moon,
the moon's illumination, and other factors, it is possible to
determine the start of a lunar month with a fairly high degree of
certainty. However, these calculations are extremely complicated and
thus slow, so most algorithms, including the one used here, are only
approximations of the true astronomical calculations. At present, the
approximations used in this class are fairly simplistic; they will be
improved in later versions of the code.

Like the Islamic religious calendar, Umm al-Qura is also based on the
sighting method of the crescent moon but is standardized by Saudi
Arabia.

Remove focus assignment as it seems unnecessary to me and breaks the

This widget looks quite app-like when open in a windowed form using the
"Windowed widgets" KRunner runner search result. When launched in that
way, it can give the user the impression that it's a real app. This
presents some issues:

1. If the user has a real calculator app installed, two calculator
results will appear in search results, which is weird and confusing.
People will wonder, "Why does KDE ship with two calculator apps"?

2. If the user has no calculator apps installed, this will appear in
search results anyway and they will think it is the official KDE
calculator app and use it instead of using the "download a calculator
app" search result from the AppStream runner. The widget is quite simple
with almost no features, which is fine for a widget. But if the user
misunderstands this and thinks it's the official KDE calculator app,
they'll be lacking those features and form an incorrect impression of
KDE's ability to write good calculator apps, because in truth, we have
two powerful high quality calculator apps (KCalc and Kalk).

This saves some memory when the calendar is not used.

No need to maintain a list of month names as libicu provides them.

Translated month names are available in https://github.com/unicode-org/icu/tree/main/icu4c/source/data/locales
