[Embeddable Rebuild] Add creation / configuration options to buildEmbeddable

[Heenawter]

Describe the feature:
Sometimes, when creating an embeddable, you need to pass in some state that is never modified after creation and does not need to be serialized. Examples include:

• isShareable and tooltipRenderer for the Maps embeddable (https://github.com/elastic/kibana/blob/main/x-pack/plugins/maps/public/react_embeddable/types.ts#L55-L58)
• showAddButton, editorConfig, etc. for the Control Group embeddable (https://github.com/elastic/kibana/blob/main/src/plugins/controls/public/control_group/types.ts#L44-L52)
• displaySettings in options list control (not technically an embeddable, but similar architecture would be followed)

This state often controls how the embeddable is rendered initially, but is never used again - we should add a way to provide this state via the buildEmbeddable callback

@Heenawter is this still needed you think? Or are the workarounds in place enough for now?

[Heenawter]

@ThomThomson We can probably close this one for now - we're refactoring state a bunch in much more meaningful ways ATM.
