[Refactor] StreamIO and OpenSearchException foundation to core library (

#8035)

This commit refactors the Stream IO classes from the server to core
library to support cloud native and serverless extensions.

The following classes are refactored:

* StreamInput
* StreamOutput
* Writeable
* NamedWriteable
* NamedWriteableRegistry
* Index
* ShardId
* BytesReference
* ByteArray
* BigArray
* SecureString
* Text
* ParsingException
* RestStatus

The namespace is left unchanged but will be refactored in a follow up
commit to avoid split package in order to support jigsaw modularity.
