[LSR] Fix matching vscale immediates (#100080) 
Somewhat confusingly a `SCEVMulExpr` is a `SCEVNAryExpr`, so can have
> 2 operands. Previously, the vscale immediate matching did not check
the number of operands of the `SCEVMulExpr`, so would ignore any
operands after the first two.

This led to incorrect codegen (and results) for ArmSME in IREE
(https://github.com/iree-org/iree), which sometimes addresses things
that are a `vscale * vscale` multiple away. The test added with this
change shows an example reduced from IREE. The second write should
be offset from the first `16 * vscale * vscale` (* 4 bytes), however,
previously LSR dropped the second vscale and instead offset the write by
`#4, mul vl`, which is an offset of `16 * vscale` (* 4 bytes).
