Introduce $ouiInfoColor and $ouiInfoLinkColor

[canascar]

Is your feature request related to a problem? Please describe.

Currently OpenSearch UI currently maps information link colors to ouiColorPrimary or ouiLinkColor. This creates a conflict in color indication when we move to Next dark/light as Primary and Secondary/Success colors map to a green tone which makes it difficult and confusing for a customer user to differentiate between the meaning of the indicated color, primarily in callouts and information related links.

Describe the solution you'd like

We would like to introduce two new variables:
$ouiInfoColor - using a color that is significantly different from $ouiColorPrimary
$ouiInfoColorLink - using a color that is significantly different from $ouiLinkColor

$ouiLinkColor / $ouiInfoLinkColor:
Next Dark: #0FABFF
Next Light: #1390E6

Describe alternatives you've considered

Additional context

Components that should map to this color:
Callout (Info)
Info button type in all styles and sizes
Health - Active state
(May add more to this list - progress?)

Adding @kgcreative for visibility

[kgcreative]

We should start with callout (info) and add a new option to toast (info)

Button & Link i would want to consider a bit more

One more request for mapping for $ouiInfoColor- informational severity level badge.
See opensearch-project/security-analytics-dashboards-plugin#760 for more details.

Badging colors are currently unaffected by this as "primary" badge color still displays as blue but we can certainly consider updating the naming schema for badging.

There is currently an Info toast, we just need to modify and add the indicator top border to it. I can add an issue for follow-up.

This issue is for adding the color variables $ouiInfoColor and $ouiInfoLinkColor. I will make separate detailed issues for components that will use these new color styles.

I can take this on!
