add missing c++ headers

[mlauss2]

Add a few missing headers which are no longer indirectly included by other headers, fixes build with gcc-14

Description

Fix build with gcc-14: add a few missing includes which are no longer included implicitly through
other headers.

Motivation and context

Fix building kodi with gcc-14, mainly due to template errors about std::find() and friends, which are
fixed by including the <algorithm> header.

How has this been tested?

Build kodi-gbm on linux x86_64 with gcc version 14.0.0 20231012 (experimental) 701363d827d45d3e3601735fa42f95644fda8b64
