build: Use more precompiled headers to reduce build time by around 50%

[slurmlord]

This change reduces the compile time of the solution by increasing the use of precompiled headers in various projects.
The prioritization of which headers to include was gained by referring to the Build Insights output of VS2022.
The following projects are changed:

• Core/Libraries/debug
• Core/Libraries/profile
• Core/Libraries/WWVegas/WWLib
• Generals/GameEngineDevice
• Generals/WW3D2
• Generals/Tools/W3DViewer
• Generals/Tools/WorldBuilder
• GeneralsMD/GameEngineDevice
• GeneralsMD/WW3D2
• GeneralsMD/Tools/W3DViewer
• GeneralsMD/Tools/WorldBuilder

The changes in Core/Libraries/debug and Core/Libraries/profile are a bit more involved than the other libraries, as the previous approach was to just include _pch.h. These have now been changed to explicitly include the headers that are needed, validated by turning precompiled headers off and see that they still compile.

Measuring the impact was done by compiling the presets vc6 and win32-debug with and without this change. 7 timing measurements was taken for each option and then averaged. The PowerShell snippet used to do this is:

# First initialize the build with one compile of the workflow to keep dependencies out of the measurements:
cmake --workflow --preset [vc6|win32-debug]
$measurements = @() ; do { cmake --build build/[vc6|win32-debug] --target clean ; $measurements += Measure-Command { cmake --build build/[vc6|win32-debug] } } while ($measurements.Length -lt 7) ; $measurements.TotalSeconds | Measure-Object -Average

The results were as follows

	vc6	win32-debug
Without change	230.92s	97.46s
With change	103.75s	56.49s
Change reduction	127.17s (-55%)	40.97s (-42%)

Very nice speed.
