feat(components): Decouple shadow from clickability [JOB-105101]

[Aiden-Brine]

Motivations

It was requested that the presence of a drop shadow on a card not depend on if the card is clickable and instead is controllable via an elevation prop. Note that this PR should be reviewed at the same time since it adds breaking changes.

Changes

Removed the drop shadow CSS from clickable cards

Added

An elevation prop to the Card component which controls if the card has a drop shadow

Changed

Cards will no longer automatically have a drop shadow if they are clickable. Instead, the presence of drop-shadow depends on the new elevation prop
