RFR: 8307651: RISC-V: Correct format typo for stringL_indexof_char instruction [v2]

[Feilong Jiang]

> Hi.
> 
> Can I have reviews for this trivial patch that fixes a typo in the format of `stringL_indexof_char` instruction? It should be `StringLatin1` instead of `StringUTF16` for `StrIntrinsicNode::L`.
