[Windows] Improve build performance on windows

[Paxxi]

Description

Using C++ Build Insights in VS2019 I recorded a build
and looked at time spent parsing header files. This PR
adds some of the slow headers to pch.

Rough numbers on before after on my machine
Debug:

• Before: 00:11:35
• After: 00:07:58

RelWithDebInfo

• Before: 00:21:48
• After: 00:17:15

measured using
msbuild kodi.sln -t:Clean -P:Configuration=RelWithDebInfo
msbuild kodi.sln -t:Build -P:Configuration=RelWithDebInfo

Just something to keep in mind for the future, native support for precompiled headers was added to CMake in 3.16: https://cmake.org/cmake/help/latest/command/target_precompile_headers.html
Once the minimum required CMake version is raised it would probably be beneficial to switch to that method to speed up compilation on all platforms.

Can you fix the ordering? https://jenkins.kodi.tv/job/BuildMulti-PR/15528/artifact/PR17671-0001-5d62d8921c-Improve-build-performance-on-windo.diff

The amount of coffee I don't drink waiting for kodi to compile is coming out of your paycheck. Nice timing stats.

When the clang commit comes first, git blame is more beautiful with relevant commit messages appearing instead of clang format lemons. For next time.
