ES Lint rules for css-in-js declarations within Kibana (#200703)
## Summary

Closes https://github.com/elastic/kibana-team/issues/1272

This PR adds implementation for eslint rules to help facilitate the
migration away from SASS files to leveraging the design tokens EUI
provides for styling.

The introduced rules  in this PR are as follows;

- #### No CSS Color values
  Consider; 

  ```tsx
  <EuiCode style={{ color: '#dd4040' }}>Hello World!</EuiCode>
  ```

this expression because it specifies the css color property, with a
valid [CSS color
value](https://developer.mozilla.org/en-US/docs/Web/CSS/color_value),
when the aforementioned rule is enabled depending on the set report
level set the user would get a feedback, see screenshot below;

This rule also works for variables defined elsewhere in the code and
referenced as a value to the style prop, see screenshot below;

feedback will also be provided when some variable that is a literal
value is specified as a value for any earmarked property that should not
specify literal values.

feedback will be provided for referencing a member prop of some object
defined elsewhere as a value to any earmarked property that we have
deemed to not specify literal values

<img width="1676" alt="Screenshot 2024-11-29 at 11 36 44"

	Supports;
	- object values
	- object references
	- template literals
	- tagged templates 

This approach does not penalize variable declarations, only the usages
of any said variable when it doesn't conform to expectation

- #### Prefer CSS attributes for EUI components (optional)
  Consider; 

  ```tsx
<EuiCode style={{ someCSSProperty: 'propertyValue' }}>Hello
World!</EuiCode>
  ```
A declaration like the one above, will be regarded as an error and can
be fixed, when it's fixed it will be re-written as
  
  ```tsx
<EuiCode css={{ someCSSProperty: 'propertyValue' }}>Hello
World!</EuiCode>
  ```
