Fix semantic functions for vsuxseg instructions and correct disasm typos

This CL ports commit 1f6702c18e15cdae3dc4615a0abf9ad1ef687bb9 from
the coralnpu-mpact-vsi repository, originally authored by Yongqi Chen.

Changes in this CL:
1. Fixes the semantic function for `vsuxsegei*` instructions in
   `third_party/mpact_riscv/riscv_vector.isa` to correctly point to
   `VsSegmentIndexed` instead of the buggy `VsSegmentStrided`. Also
   updates inline comments to use `/*index_width*/`.
2. Fixes widespread copy-paste bugs across `riscv_vector.isa` and
   `learning/brain/research/kelvin/sim/coralnpu_v2.isa` where ordered
   segment instructions (`vsoxseg`, `vloxseg`) were inaccurately
   configured to disassemble as `vsuxseg` and `vluxseg`.
