[Dashboard] Editing toolbar update

[cqliu1]

Summary

Related to #144418.
Closes #160800.

This makes all of the buttons in the editor toolbar small/compressed for a slightly sleeker look. These changes only affect the toolbar in Dashboard and don't change the toolbar appearance in Canvas. I've also removed the quick actions and renamed Select type to Add panel.

Risk Matrix

Delete this section if it is not applicable to this PR.

Before closing this PR, invite QA, stakeholders, and other developers to identify risks that should be tested prior to the change/feature release.

When forming the risk matrix, consider some of the following examples and how they may potentially impact the change:

Risk	Probability	Severity	Mitigation/Notes
Multiple Spaces—unexpected behavior in non-default Kibana Space.	Low	High	Integration tests will verify that all features are still supported in non-default Kibana Space and when user switches between spaces.
Multiple nodes—Elasticsearch polling might have race conditions when multiple Kibana nodes are polling for the same tasks.	High	Low	Tasks are idempotent, so executing them multiple times will not result in logical error, but will degrade performance. To test for this case we add plenty of unit tests around this logic and document manual testing procedure.
Code should gracefully handle cases when feature X or plugin Y are disabled.	Medium	High	Unit tests will verify that any feature flag or plugin combination still results in our service operational.

Hmm... Do we want to do this for just Dashboard? It seems out of place that only one app would use a compressed version of the toolbar while all other apps (Canvas, Lens, etc) use the full height buttons 👀 Maybe I misunderstood in our meeting, but I assumed the requests for a compressed layout were referring to horizontal space and not vertical?

While you are in the neighborhood, can we remove that double border between the icon-only set of buttons? It was not there originally and was the result of some other change along the way.

@ryankeairns I'm gonna hold off on merging this until we land on a design for #144418, but I can open a PR just to fix that double border bc it's been bothering me too haha. The border radius also slightly differs between the button group and the rest of the toolbar buttons. I'll see if I can fix that too.

LGTM!

@teresaalvarezsoler I've updated the add panel menu order. Is this correct?

Looks good! Thanks

Great looking and straightforward changes! Tested locally and looked through the code and everything LGTM!

[ThomThomson]

Nice call to have the size here default to medium. That way we don't have to change Canvas at all.
