  [NFC][VPlan] Add initial tests for future VPlan-based stride MV (#182594)

I tried to include both the features that current
LoopAccessAnalysis-based transformation supports (e.g., trunc/sext of
stride) but also cases where the current implementation behaves poorly,
e.g., https://godbolt.org/z/h31c3zKxK; as well as some other potentially
interesting scenarios I could imagine.

The are two test files with the same content. One is for VPlan dump
change of the future transformation alone (I'll update
`-vplan-print-after` in the next PR), another is for the full vectorizer
pipeline. The latter has two `RUN:` lines:
* No multiversioning, so the next PR diff can show the transformation
itself
* Stride multiversionin performed in LAA, so that we can compare next
PR's
VPlan-based transformation vs old behavior.
