Support references in convert_to_*

conver_to_* functions now accept REFERENCE values, which will be
unwrapped before performing the usual conversion. This is consistent
with convert_scalar_to_number and matches the expected behavior in
a couple random use-sites I checked.

Also includes a couple fixes/cleanups elsewhere and two tests for
cases that previously didn't work (though the reference issue existed
all over the place).

Get rid of more ZVAL_ZVAL() macros

Avoid zval duplication in ZVAL_ZVAL() macro (it was necessary only in few places).
Switch from ZVAL_ZVAL() to simpler macros where possible (it makes sense to review remaining places)

Make convert_to_* safe with rc>1

This only involves switching zval_dtor to zval_ptr_dtor for arrays
and making the convert_to_object for arrays a bit more generic.

Make convert_to_* safe with rc>1

This only involves switching zval_dtor to zval_ptr_dtor for arrays
and making the convert_to_object for arrays a bit more generic.

All the other changes outside zend_operators.c just make use of
this new ability (use COPY instead of DUP).

What's still missing: Proper references handling. I've seen many
convert_to* calls that will break when a reference is used.

Also fixes bug #69788.

Changed HashTable layout:

Removed HashTable->arHash (reduced memory consumption). Now hash slots may be accessed using HT_HASH() macro.
Hash slotas are allocated together with Buckets (before them) and lay in reverse order from HashTable->arData base address (see comments in Zend/zend_types.h)
Indexes in hash table and conflict resolution chains (Z_NEXT) may be stored as indeces or offsets in bytes, depending on system (32 or 64-bit).
HashTable data filelds are reordered to keep the most useful for zend_hash_find() data in the same CPU cache line.

Change "foreach" statement behavior (this is just a PoC yet)

- "foreach by value" don't relay on internal array/object pointer and doesnt perform array duplication. It just locks it incrementing reference counter. If the original array is modified by some code, the copy on write is performed and "foreach" still work with the old copy.

- it makes no difference if array given to "foreach by value" is reference itself

- "foreach by reference" still use internal array/object pointer and should work similar to PHP-5. (This id not completely implemented)
