Reviewed by Mark Lam.

This patch adds WTF::charactersContain SIMD function which scans entire string to check if one of character is included.
This function is aligned to charactersAreAllASCII. The intention of this new function is assuming that the given characters rarely
include specified characters. So this function super quickly scans entire string and returning the answer with SIMD.
