[PATCH] telemetry: make socket handler typedef private

[Bruce Richardson <bruce.richardson@intel.com>]

The socket handler typedef, just called "handler" does not belong in the
public namespace, especially since it is unprefixed. Rename to
"telemetry_sock_handler" and move to internal header.

Doing so also clears shadowing warnings in dmadev library, when it is
built with -Wshadow.

Fixes: 6dd571fd07c3 ("telemetry: introduce new functionality")

NOTE: This patch was originally submitted as part of series[1], but I
think this is a serious enough fix to consider taking into 25.11.
