[jdk18] RFR: 8279222: Incorrect legacyMap.get in java.security.Provider after JDK-8276660 [v2]

[Aleksey Shipilev]

> SonarCloud reports:
>  A "Map<ServiceKey, Service>" cannot contain a "String" in a "ServiceKey" type.
> 
> 
>      // clean up old alias if present
>      Service prevAliasService = legacyMap.get(aliasAlg);
> 
> 
> Should be `aliasKey`, like other accesses to `legacyMap`. This code is introduced by [JDK-8276660](https://bugs.openjdk.java.net/browse/JDK-8276660), so it affects JDK 18.
> 
> Additional testing:
>  - [x] Linux x86_64 fastdebug `jdk_security`
