chore(compass-components): refactor ItemActionControls #2

[kraenhansen]

Description

Follow-up to #6552.

Merging this PR will:

• Replace &:not(:first-child) styling to add spacing between item action buttons with the use of flex gap on the container element.
• Add strong typing for 3x onClick handlers accessing data-action attributes on the element being clicked.
• Remove Actions generic type parameters where it didn't add additional guarantees
• Provide default type argument for Actions generic type to simplify use internally in the ./actions directory.
• Remove unneeded / extraneous memoization.
