[YARR] Add latin1Table for efficient Char8 filtering
https://bugs.webkit.org/show_bug.cgi?id=317989
rdar://180768852
Reviewed by Sosuke Suzuki.
Let's have ByteTable-based latin1-table which converts CharacterClass
matching to table-based one when it is Char8 and matching is
complicated. We use ByteTable for now as BitSet based one is slower than
this ByteTable-based one.
