Hi, Internals

I would like adds locale parameter that already there are grapheme_* functions.
Because Unicode is locale-dependency but grapheme_* functions is not
locale-dependency.

For example, Add $locale parameter is below.
```
grapheme_extract(
    string $haystack,
    int $size,
    int $type = GRAPHEME_EXTR_COUNT,
    int $offset = 0,
    int &$next = null,
    string ?$locale = null
): string|false
grapheme_str_split(string $string, int $length = 1, string ?$locale =
null): array|false
grapheme_stripos(string $haystack, string $needle, int $offset = 0,
string ?$locale = null): int|false
grapheme_stristr(string $haystack, string $needle, bool $beforeNeedle
= false, string ?$locale = null): string|false
grapheme_strlen(string $string, ?string $locale = null): int|false|null
grapheme_strpos(string $haystack, string $needle, int $offset = 0,
string ?$locale = null): int|false
grapheme_strripos(string $haystack, string $needle, int $offset = 0,
string ?$locale = null): int|false
grapheme_strrpos(string $haystack, string $needle, int $offset = 0,
string ?$locale = null): int|false
grapheme_strstr(string $haystack, string $needle, bool $beforeNeedle =
false, ?$locale = null): string|false
grapheme_substr(string $string, int $offset, ?int $length = null,
?string ?$locale = null): string|false
```

What do you think?
I would like go to write an RFC if this is fine.

Regards
Yuya
