Description

This PR adds a new Scalar object to pylibcudf that will function as the pylibcudf equivalent of cudf::scalar. Unlike columns, which are typically operated on in the form of views rather than owning types by libcudf, owning scalars are accepted by (const) ref by libcudf APIs and no corresponding view type exists. Therefore, pylibcudf.Scalar differs from pylibcudf.Column by actually owning an instance of the underlying libcudf type (cudf::scalar). Construction of pylibcudf Scalars is expected to be done from an Arrow scalar.

This PR relies on #14124 and should not be merged until after that one.

Mostly minor comments with one issue to do with memory-resource management going back and forth between py- and libcudf

Thanks! Good to go from my side. I think we can just open a doc issue for the outstanding comment about the @no_gc_clear decorator.
