[RISCV][TTI] Model cost for insert/extract into illegal types (#106440)
We'd previously just deferred to the base implementation, but that more
or less always returns 1. This underestimates the cost of the
insert/extract, biases the SLP vectorizer towards forming illegally
typed vectors, and underestimates the cost of scalarized operations
(like unaligned scatter/gather).
