Fix GH-14732: date_sun_info() fails for non-finite values

Fix GH-14732: date_sun_info() fails for non-finite values

`timelib_astro_rise_set_altitude()` is not prepared to deal with non-
finite values (`nan`, `inf` and `-inf`) for `lon` and `lat`; instead
these trigger undefined behavior. Thus we catch non-finite values
before even calling that timelib function; for `date_sun_info()` we
trigger `ValueError`s; for `date_sunrise()` and `date_sunset()` we
silently return `false`, since these functions will be sunsetted
anyway.

Closes GH-16497.

Fixed bug GH-16037 (Assertion failure in ext/date/php_date.c)

Fix GH-16454: Unhandled INF in date_sunset() with tiny $utcOffset

After normalization, `N` is supposed to be in range [0, 24], but for
very large and very small `$utcOffset` this is not

Fix GH-16454: Unhandled INF in date_sunset() with tiny $utcOffset

After normalization, `N` is supposed to be in range [0, 24], but for
very large and very small `$utcOffset` this is not necessarily the
case, since the normalization might yied `-inf` or `inf`. If that
happens, we let the function fail silently, since it is highly unlikely
that such `$utcOffset`s are passed in practice.

Closes GH-16483.
