Document NIO channel socket addresses

[jonathanpeppers]

Summary

• Document the local and remote socket-address properties on DatagramChannel and SocketChannel, plus the local socket-address property on ServerSocketChannel.
• Retain the unresolved binding-only placeholders for follow-up work; the scoped namespace still contains 406 To be added placeholders.

• https://developer.android.com/reference/java/nio/channels/DatagramChannel#getLocalAddress()
• https://developer.android.com/reference/java/nio/channels/DatagramChannel#getRemoteAddress()

• https://developer.android.com/reference/java/nio/channels/SocketChannel#getRemoteAddress()
• https://developer.android.com/reference/java/nio/channels/ServerSocketChannel#getLocalAddress()

Validation

• Parsed all three modified XML files with PowerShell's [xml] cast.
• Ran git diff --check.
• Confirmed docs/xml/index.xml is unchanged.
