Message:

Emoji: Improve performance when encoding or staticizing emoji.

Both wp_encode_emoji() and wp_staticize_emoji() perform a PHP version check when deciding how to apply their behaviour, but this check only needs to happen once, rather than every time in their internal looks.

Moving the check outside of the loop reduces processing time by 50%.

Props johnbillion.
Fixes #45930.
