VectorRepeatValue support for Logical Expressions

[onelson]

Work done in #4960 added the new vector support for certain literals, but only properly added the runtime support in binary expressions.

Logical expressions need to be updated to handle VectorRepeatValue. For this to happen, we must first support vectorization of boolean literals.

DOD:

• boolean literals can be vectorized.
• logical expressions correctly handle VectorRepeatValue inputs.

I've got a draft PR up for this, but don't want to merge until we're closer to getting boolean literals to work with vectorized code. #4998

[onelson]

This issue was originally written to track "unknown work" but it looks like the broad strokes of what was needed beyond binary expressions fell into 2 categories:

• unary expressions (tracked by Vectorize unary Add, Sub, Exists, Not #5045)
• logical expressions (this issue)

Rephrasing the description to cover just the logical expression and the prerequisite boolean literal work.

If it all comes together in #4998 we can probably close #4997 as duplicate.
