Zend: add missing ZPP tests

Effectively continuing the work started in #23192.

This is a good first issues for newcomers.

The missing specifiers are:

• Z_PARAM_ENUM(dest, _ce)
• old "a"
  • Z_PARAM_ARRAY_EX2(dest, check_null, deref, separate)
  • Z_PARAM_ARRAY_EX(dest, check_null, separate)
  • Z_PARAM_ARRAY(dest)
  • Z_PARAM_ARRAY_OR_NULL(dest)
• old "A"
  • Z_PARAM_ARRAY_OR_OBJECT_EX2(dest, check_null, deref, separate)
  • Z_PARAM_ARRAY_OR_OBJECT_EX(dest, check_null, separate)
  • Z_PARAM_ARRAY_OR_OBJECT(dest)
• old "h"
  • Z_PARAM_ARRAY_HT_EX2(dest, check_null, deref, separate)
  • Z_PARAM_ARRAY_HT_EX(dest, check_null, separate)
  • Z_PARAM_ARRAY_HT(dest)
  • Z_PARAM_ARRAY_HT_OR_NULL(dest)
• array|int:
  • Z_PARAM_ARRAY_HT_OR_LONG_EX(dest_ht, dest_long, is_null, allow_null)
  • Z_PARAM_ARRAY_HT_OR_LONG(dest_ht, dest_long)
  • Z_PARAM_ARRAY_HT_OR_LONG_OR_NULL(dest_ht, dest_long, is_null)
• array|string:
  • Z_PARAM_ARRAY_HT_OR_STR_EX(dest_ht, dest_str, allow_null)
  • Z_PARAM_ARRAY_HT_OR_STR(dest_ht, dest_str)
  • Z_PARAM_ARRAY_HT_OR_STR_OR_NULL(dest_ht, dest_str)
• old "H"
  • Z_PARAM_ARRAY_OR_OBJECT_HT_EX2(dest, check_null, deref, separate)
  • Z_PARAM_ARRAY_OR_OBJECT_HT_EX(dest, check_null, separate)
  • Z_PARAM_ARRAY_OR_OBJECT_HT(dest)
• old "f"
  • Z_PARAM_FUNC_EX2(dest_fci, dest_fcc, check_null, deref, free_trampoline)
  • Z_PARAM_FUNC_EX(dest_fci, dest_fcc, check_null, deref)
  • Z_PARAM_FUNC(dest_fci, dest_fcc)
  • Z_PARAM_FUNC_NO_TRAMPOLINE_FREE(dest_fci, dest_fcc)
  • Z_PARAM_FUNC_OR_NULL(dest_fci, dest_fcc)
  • Z_PARAM_FUNC_NO_TRAMPOLINE_FREE_OR_NULL(dest_fci, dest_fcc)
• old "p"
  • Z_PARAM_PATH_EX(dest, dest_len, check_null, deref)
  • Z_PARAM_PATH(dest, dest_len)
  • Z_PARAM_PATH_OR_NULL(dest, dest_len)
• old "P"
  • Z_PARAM_PATH_STR_EX(dest, check_null, deref)
  • Z_PARAM_PATH_STR(dest)
  • Z_PARAM_PATH_STR_OR_NULL(dest)
• old "s"
  • Z_PARAM_STRING_EX(dest, dest_len, check_null, deref)
  • Z_PARAM_STRING(dest, dest_len)
  • Z_PARAM_STRING_OR_NULL(dest, dest_len)
• old "S"
  • Z_PARAM_STR_EX(dest, check_null, deref)
  • Z_PARAM_STR(dest)
  • Z_PARAM_STR_OR_NULL(dest)
• string|int
  • Z_PARAM_STR_OR_LONG_EX(dest_str, dest_long, is_null, allow_null)
  • Z_PARAM_STR_OR_LONG(dest_str, dest_long)
  • Z_PARAM_STR_OR_LONG_OR_NULL(dest_str, dest_long, is_null)
• old "z"
  • Z_PARAM_ZVAL_EX2(dest, check_null, deref, separate)
  • Z_PARAM_ZVAL_EX(dest, check_null, separate)
  • Z_PARAM_ZVAL(dest)
  • Z_PARAM_ZVAL_OR_NULL(dest)
• old "+" and "*"
  • Z_PARAM_VARIADIC_EX(spec, dest, dest_num, post_varargs)
  • Z_PARAM_VARIADIC(spec, dest, dest_num)
  • Z_PARAM_VARIADIC_WITH_NAMED(dest, dest_num, dest_named)

Start by reviewing the work from issue #23192 and the listed Zend parameter-parsing specifiers. Add coverage for the unchecked macros and variants, then verify that the corresponding ZPP tests cover each listed case.
