Untangle the epic precompiled.h mess Don't include the lazy precompiled.h everywhere, only what's required for the compilation unit. platform.h needs to be included instead to provide all essential defines and types. All includes use the relative path to the neo or the game specific root. Move all idlib related includes from idlib/Lib.h to precompiled.h. precompiled.h still exists for the MFC stuff in tools/. Add some missing header guards.

Always compile all SIMD code Protect all SIMD implementations with the according defines and let the compiler decide if it supports the intructions. Linux will still use Simd_Generic because CPU feature runtime detection is missing.

Fix -Woverloaded-virtual warnings We want to use the SIMD functions of the base class if the deriving class does not implement every overloaded variant. Added missing idLight::SetColor(idVec3) which is declared in idEntity.

Disable broken idSIMD_SSE::UpSampleOGGTo44kHz() It corrupted the stack when called with buffers allocated on the stack and numSamples that are not a multiple of four, apparently, by writing 4 floats too many, at least in the 22KHz Stereo case.. This caused the crash described in https://github.com/dhewm/dhewm3/issues/303#issuecomment-678809662 Now it just uses the generic C code, like all platforms besides MSVC/x86 already do.
