JavaDocs: Document replacement methods for MKP methods

### Issue
Crypto Tools marked all MasterKeyProvider methods as deprecated, but did not revise their JavaDocs to state which methods should be used instead.

This is a source of customer confusion, as it is not clear that customers should use the Keyring methods instead.

_As originally posted by @jumarko in https://github.com/aws/aws-encryption-sdk-java/pull/1864#discussion_r1665561054_

Are these deprecations documented anywhere?
The javadoc doesn't say anything about what should be used instead.

### Suggested Fix
Revise the Java Docs for the Master Key Providers so that they details which methods replace the marked as deprecated methods.

Either remove the deprecation notice from the Caching Cryptographic Materials Manager methods or [implement support for the CachingCMM with Keyrings](https://github.com/aws/aws-cryptographic-material-providers-library/issues/480).

Localiza los JavaDocs de los métodos obsoletos de MasterKeyProvider y de los métodos de Caching Cryptographic Materials Manager. Lee las issues relacionadas 2035 y 2033 y, después, compara las APIs obsoletas con los métodos de Keyring a los que hacen referencia. Se considera terminado cuando se haya documentado el reemplazo de cada método obsoleto y la cuestión de Caching CMM se haya resuelto o documentado claramente.
