### Description

Currently, the [`tryAuthenticateToken`](https://github.com/elastic/elasticsearch/blob/55088d154d1764a6d4fa8e9078bde9da1e9ff9a5/x-pack/plugin/security/src/main/java/org/elasticsearch/xpack/security/authc/TokenService.java#L458) method calls `decodeAndValidateToken` which ends up sending two `GetRequest` for the same token ID. First in [`decodeToken`](https://github.com/elastic/elasticsearch/blob/55088d154d1764a6d4fa8e9078bde9da1e9ff9a5/x-pack/plugin/security/src/main/java/org/elasticsearch/xpack/security/authc/TokenService.java#L602) and second in [`checkIfTokenIsValid`](https://github.com/elastic/elasticsearch/blob/55088d154d1764a6d4fa8e9078bde9da1e9ff9a5/x-pack/plugin/security/src/main/java/org/elasticsearch/xpack/security/authc/TokenService.java#L1977). The second call is unnecessary as we already fetched the access token in the first call, it's just simply dropped. We should refactor these two methods to avoid sending second get request just to validate the access token.
