Avoid crash for reset/end/next/prev() on ffi classes (#9711)

(And any PECLs returning `zend_empty_array` in the handler->get_properties
overrides)

Closes GH-9697

This is similar to the fix used in d9651a941915eb5fb5ad557090b65256fd8509b6
for array_walk.

This should make it safer for php-src (and PECLs, long-term) to return
the empty immutable array in `handler->get_properties` to avoid wasting memory.
See https://github.com/php/php-src/issues/9697#issuecomment-1273613175

The only possible internal iterator position for the empty array is at the end
of the empty array (nInternalPointer=0).
The `zend_hash*del*` helpers will always set nInternalPointer to 0 when an
array becomes empty,
regardless of previous insertions/deletions/updates to the array.

Make array_pad's $length warning less confusing (#10149)

Remove array_pad's arbitrary length restriction

The error message was wrong; it *is* possible to use a larger length.
Furthermore, there is an arbitrary restriction on the new array's
length.

Fix both by checking the length against HT_MAX_SIZE.

Fix GH-9296: `ksort` behaves incorrectly on arrays with mixed keys

The comparator function used at ksort in SORT_REGULAR mode
need to be consistent with basic comparison rules. These rules
were changed in PHP-8.0 for numeric strings, but comparator
used at ksort kept the old behaviour. It leads to inconsistent
situations, when after ksort the first key is GREATER than some
of the next ones by according to the basic comparison operators.

Closes GH-9293.

Fix GH-9244: Segfault with array_multisort + array_shift

After restructuring non-packed arrays, we either need to pack them if

Avoid unnecessary comparison

The first element of the `arrays` serves as base for the comparison, so
there is no need to compare it to itself.

Whenever ->last_unsafe is set to `true` an exception has been thrown. Thus we

which is a much more natural way to ommunicate an error up the chain.

Use more compact representation for packed arrays.

- for packed arrays we store just an array of zvals without keys.
- the elements of packed array are accessible throuf as ht->arPacked[i]
instead of ht->arData[i]
- in addition to general ZEND_HASH_FOREACH_* macros, we introduced similar
familied for packed (ZEND_HASH_PACKED_FORECH_*) and real hashes
(ZEND_HASH_MAP_FOREACH_*)
- introduced an additional family of macros to access elements of array
(packed or real hashes) ZEND_ARRAY_ELEMET_SIZE, ZEND_ARRAY_ELEMET_EX,
ZEND_ARRAY_ELEMET, ZEND_ARRAY_NEXT_ELEMENT, ZEND_ARRAY_PREV_ELEMENT
- zend_hash_minmax() prototype was changed to compare only values

Because of smaller data set, this patch may show performance improvement
on some apps and benchmarks that use packed arrays. (~1% on PHP-Parser)

TODO:
- sapi/phpdbg needs special support for packed arrays (WATCH_ON_BUCKET).
- zend_hash_sort_ex() may require converting packed arrays to hash.
