  [SandboxIR][SandboxVec] Remove score tracking from Region, add RegionWithScore (#190293)

Up until now the `Region` class contained a `ScoreBoard` and was
tracking instruction costs by default. However, design-wise the Region
is a generic IR-level structure and should be independent from score
tracking.

So this patch removes the score tracking capability from the base
`Region` class and creates a separate `RegionWithScore` derived class
for that. The new class is placed in the vectorizer directory because
the score tracking is meant for the vectorizer.

Should be NFC.
