Fixes among others:
. Bug #79580 (date_create_from_format misses leap year).
. Bug #80974 (Wrong diff between 2 dates in different timezones).
. Bug #81097 (DateTimeZone silently falls back to UTC when providing an offset with seconds).
. Bug #81273 (Date interval calculation not correct).
These are deprecated in favor of date()/DateTime::format() (for
locale-indendent formatting) and IntlDateFormatter::format()
(for locale-dependent formatting).

This deprecates passing null to non-nullable scale arguments of
internal functions, with the eventual goal of making the behavior
consistent with userland functions, where null is never accepted
for non-nullable arguments.
This change is expected to cause quite a lot of fallout. In most
cases, calling code should be adjusted to avoid passing null. In
some cases, PHP should be adjusted to make some function arguments
nullable. I have already fixed a number of functions before landing
this, but feel free to file a bug if you encounter a function that
doesn't accept null, but probably should. (The rule of thumb for
this to be applicable is that the function must have special behavior
for 0 or "", which is distinct from the natural behavior of the
parameter.)

Closes GH-6475.
* Remove usage of strftime() in favor of date() in cases where
we are not specifically testing strftime(). We implement
date() ourselves, and as such are insulated from implementation-
defined behavior.
* Add skipif for broken strftime() %Z support. We have decided
not to work around the issue for musl using manual expansion,
as people should not be using this function anyway, and it is
slated for future deprecation.
* Don't test strftime() with invalid format specifier. The
behavior is implementation-dependent.
Also fixes similar issues for DateTimeImmutable::createFromFormat,
DateTime::createFromImmmutable, DateTime::createFromInterface,
DateTimeImmutable::createFromMutable, and
DateTimeImmutable::createFromInterface.
