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.

Use ZEND_UNREACHABLE() instead of ZEND_ASSERT(0)

Instead of marking unreachable code with `ZEND_ASSERT(0)`, we introduce
`ZEND_UNREACHABLE()`, so that MSVC which does not consider `assert(0)`
to mark unreachable code does no longer trigger C4715[1] warnings in
debug builds. This may be useful for other compilers as well.

Fix phpdbg watchpoints wrt. negative_array_index RFC

The implementation of that RFC changed the initial value of
`zend_array.nNextFreeElement` to `-1`; we work around that by inserting

We also fix the erroneous printf specifier for the unsigned integer.

* Properly initialize PHPDBG_G(watch_tmp)

* Deactivate potentially remain

Fix several mostly Windows related phpdbg bugs

* Properly initialize PHPDBG_G(watch_tmp)

Otherwise that may cause segfaults in ZTS builds.

* Deactivate potentially remaining watchpoints after REPL

Otherwise the memory could still be protected, resulting in segfaults
during shutdown.

* NULL zend_handlers_table after freeing

As of commit 4130fe4[1], the `zend_handlers_table` is explicitly
freed in the `zend_vm_dtor()`. Since phpdbg (and maybe some other
SAPIs) may restart the engine afterwards, we have to make sure that
the table is also NULLed.

* Only set context option if there is a context

In other words, we must not follow the null pointer.

* Cater to file handles without attached console

File handles do not necessarily have an attached console (for
instance, pipes do not), in which case `GetConsoleScreenBufferInfo()`
fails. In this case we set a default value (`40`) for lines like on
other systems.
