  [RISCV] Fix incorrect lowering of VECTOR_INTERLEAVE on fixed vectors (#212642)

This is the sibling patch of #207254, as it turns out VECTOR_INTERLEAVE
has the same problem on fixed vectors as well.

Instead of converting individual operands into scalable vectors, this
patch puts each of the operands directly onto stack using the fixed
vector version of segmented store intrinsics, before loading them back.
