feat: add support to display both solid and hollow static points

[madelineluke]

Description

Before this change, the Line chart could only display all solid static points, or all hollow (sparkline) static points. This update makes it so both types of static points can display on the line. The user can use the staticPoint prop that already exists to key to a property in the data that is set to either 'solid' or 'hollow'.

Motivation and Context

Allows 2 different types of static points to display on the line at the same time.

Solid points aren't in the s2 design spec, do we need to support this feature for both the s1 and s2 packages?
