Commit 4246c06 removes the restriction of not crossing the 128-bit block boundaries on RVV/SVE (as mentioned in #3618 (comment)).

Commit 4c32343 prefers use of Dup128VecFromValues instead of LoadDup128 to improve the codegen on some targets.

Both improvements are conditionally guarded for Highway 1.1.0 to avoid having to bump our minimum required version.
