[Maps] LayerControl read only mode

[nreese]

This PR adds isReadOnly mode to the ui store. When true,

1. LayerControl does not display Add layer button
2. TOC layers can not be sorted
3. layer details panel can not be opened.

The reason for large number of changes is this PR starts to add jest snapshot tests for the LayerControl to verify isReadOnly flag does the above actions.

This is a known issue that is getting addressed in EUI - elastic/eui#1571 and will go away with an EUI upgrade. The PR switches button to EuiLink for the TOCEntry and color text is currently unsupported until the EUI PR is merged.

To test, just manually edit

kibana/x-pack/plugins/maps/public/store/ui.js

Line 22 in e4e3a44

isReadOnly: false,

and set isReadOnly mode to true

nice. +1 on just managing this in the store as opposed to getting this setting from some static module function. it will keep it aligned with the other UI-state.

@nreese if a role has read only access to a space, is this the mode that will now be presented to them?

[alexfrancoeur]

And if so, would it close this in your opinion? #30313

Not yet. Lets keep #30313 open until we wire together the user roles and isReadOnly
