[Windows] Bump libxml2 to 2.15.1 / libplist to 2.7.0

[thexai]

Description

• Bump libxml2 to 2.15.1
• Bump libplist to 2.7.0

Motivation and context

Windows dependencies update.

Allows remove Windows only patch in libxslt necessary before due different libxml2 cmake namespace in Windows.
Now is LibXml2::LibXml2 in all platforms.

Maybe libxml2 namespace change has some impact in libbluray PR (not tested). Tested and not affects.

Requires upload these packages to mirrors:

libplist-2.7.0-arm64-v143-20260211.7z      
libplist-2.7.0-win32-v143-20260211.7z      
libplist-2.7.0-x64-v143-20260211.7z        
libxml2-2.15.1-arm64-v143-20260211.7z      
libxml2-2.15.1-win10-win32-v143-20260211.7z

Kodiai Review Summary

Medium
project/BuildDependencies/scripts/0_package.target-win10-arm.list (22): win10-arm platform not updated with libxml2 2.15.1
The win10-arm package list still references libxml2-2.9.9-win10-arm-v141-20200105.7z while all other platforms have been updated to 2.15.1. This creates an inconsistency where the win10-arm platform would continue using the old libxml2 version. If this platform is still supported, it should be updated to maintain consistency. If it's deprecated, this should be documented or the platform files removed.
