Windows: improve compatibility to build for UWP / Xbox

Feature or enhancement

Proposal:

• Add alternative UWP API functionality when available.
• Modernize the Windows code when there are alternatives that are also compatible with UWP.
• Add additional guards for Windows code that not builds for UWP.

The final goal is able to build for Xbox and reduce the patches required in Kodi --> Upstream some generic UWP patches here.

I propose upload small patches geared towards specific targets and always keeping current Windows functionality untouched.

Has this already been discussed elsewhere?

Comece revisando os PRs vinculados, especialmente as alterações relacionadas ao Windows e ao UWP, para verificar quais partes da proposta já estão cobertas. Rastreie os caminhos de código do Windows afetados pelas alternativas da API do UWP e pelos build guards. Considera-se concluído quando o CPython puder ser compilado para UWP/Xbox, preservando a funcionalidade atual do Windows e reduzindo os patches downstream.
