Default normalization is NFD, not NFC as stated (on PHP 7.4)

[bafetk]

Using PHP 7.4, Patchwork/utf8 claims NFC as the default normalization. However, it is hardcoded to use "4" as the normalization. This is actually NFD.

Here are the constant values in PHP 7.4:
Normalizer::FORM_C => 16
Normalizer::FORM_D => 4
Normalizer::FORM_KC => 32
Normalizer::FORM_KD => 8
Normalizer::NONE => 2

Good catch, would you mind sending a PR to fix this?

Actually, the default is still NFC, because we don't use the value of native constants.
I'm still singing values with latest PHP versions.
Thanks for the report.
