[php-src] PR #24619: Fix GH-24579: Validate option_array type before accessing as hash table

Pull Request: https://github.com/php/php-src/pull/24619 Author: paezraphael Calling filter_var() with FILTER_VALIDATE_INT crashed when the input object implemented __toString() and modified the options array referenced by the filter arguments during string conversion. The FETCH_*_OPTION macros checked if option_array was non-null but did not validate it was an array before using Z_ARRVAL_P(). When __toString() mutated the reference to a string, the code attempted to access it as a hash table, causing a crash (SIGSEGV in non-debug builds, assertion failure in debug builds). This commit adds a Z_TYPE_P(option_array) == IS_ARRAY check to FETCH_LONG_OPTION, FETCH_DOUBLE_OPTION, and FETCH_STRING_OPTION to ensure the type is an array before accessing as a hash table. Added regression test GH-24579. Fixes GH-24579. Generated with [Devin](https://devin.ai)
