Bumping EUI to v60.1.2. (elastic#135373)

* Bumping EUI to v60.1.0.

* Bumping to bugfixed v60.1.1.

* Updating snapshots for EUI Emotion changes.

* Updating a theme icon size declaration.

* Updating tests for Emotion and new EUI theme objects.

* Updating Lens drag and drop to account for Emotion wrapper.
* Updating icon size in EUI theme object for test.
* Updating Lens Editor Frame test to assert 1 click instead of 2.

* Updating two Jest tests for Emotion extra wrapper.

* Changing a Cypress selector for Emotion classnames.

* Update removed EuiIcon classes

-isLoaded was deprecated in favor of data-attrs - hook should still work

* Remove static EuiIcon classes from static SVG

- these classNames no longer output meaningful CSS and should not be used

* Fix theme JSON imports not to rely on any iconSizes keys

- (which will soon be deprecated by Emotion conversion)
- use the generic euiSizes instead, which will likely be the last to be deprecated

* Fix one more euiIcon-isLoaded className change

- we should be using the `data-is-loaded` attribute that it was switched to

* Bumping EUI to 60.1.2 patch release.

* Updating Storyshots for EUI 60.1.2.

* Removing two assertions from instances_table.spec to match localhost instance UI.
