[Security Solution][Detections] Fixes Risk Score and Severity mapping…

… issues (#73233) ## Summary Fixes the following issues around Risk Score/Severity mapping: * Severity override option cannot be unselected during rule creation * Risk score override option cannot be unselected during rule creation * Cannot fill Critical Severity override at the first attempt * Cannot create a rule with just a Critical severity override Note: When editing rules there is the possibility of the mapping fields remaining `disabled` as they are locked to the 'isLoading' flag from the gql `useFetchIndexPatterns` call, which can sometimes not return/get stuck as loading. @patrykkopycinski has a draft PR to fix this here: #73199 cc @MadameSheema ##### Severity Mapping Fixes: <p align="center"> <img width="500" src="https://user-images.githubusercontent.com/2946766/88497829-b653de00-cf7e-11ea-8e14-c351117b4282.gif" /> </p> Now distinguishes between empty string/value <p align="center"> <img width="500" src="https://user-images.githubusercontent.com/2946766/88497776-94f2f200-cf7e-11ea-821e-3766b7bed3dc.png" /> </p> ##### Risk Score Mapping Fixes: <p align="center"> <img width="500" src="https://user-images.githubusercontent.com/2946766/88497842-c075dc80-cf7e-11ea-8c41-606b20a6ac1c.gif" /> </p> ### Checklist Delete any items that are not applicable to this PR. - [X] Any text added follows [EUI's writing guidelines](https://elastic.github.io/eui/#/guidelines/writing), uses sentence case text and includes [i18n support](https://github.com/elastic/kibana/blob/master/packages/kbn-i18n/README.md) - [X] [Documentation](https://github.com/elastic/kibana/blob/master/CONTRIBUTING.md#writing-documentation) was added for features that require explanation or tutorials * Working with @benskelker on API docs. This PR adds `risk_score` (can be `undefined`) to `risk_score.mapping` for future compatibility with mapping to specific risk score values. - [X] [Unit or functional tests](https://github.com/elastic/kibana/blob/master/CONTRIBUTING.md#cross-browser-compatibility) were updated or added to match the most common scenarios
