Zend/zend_types.h: move `zend_rc_debug` to `zend_rc_debug.h`

`zend_rc_debug` is not a type and does not really belong in
`zend_types.h`; this allows using `ZEND_RC_MOD_CHECK()` without
including the huge `zend_types.h` header and allows decoupling
circular header dependencies.

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.

Check linker compatibility directly from HMODULE

Checking the linker compatibility with extranous `ImageLoad()` calls is
possible, but unnecessary, since the modules are either already loaded
or loaded shortly afterwards, so that we can get the required
information directly from the module handles. And actually, doing
`ImageLoad()` as well as `LoadLibrary()` leaves a tiny room for a race
condition, because both functions will lookup the module in the search
path, so there is no *guarantee* that both are dealing with the same
module. Dropping the `ImageLoad()` calls also has the advantage to no
longer face the issue reported in bug #79557. A very minor additional
advantage is that we no longer have to link against Imagehlp.dll.

Furthermore, there is no need to check for CRT compatibility multiple
times, so we can simplify the signature of `php_win32_crt_compatible`,
and at the same time clean up main.c a bit.

These changes require to change the signature of the exported
`php_win32_image_compatible` and `php_win32_crt_compatible` functions,
which now expect a `HMODULE` and nothing, respectively, instead of the
module name.
