* Remove fix16.h/cpp and utilise library from m_fixed.h.
* Extend m_fixed.h with two inline functions for int to/from float operations.
* Replace fix16_floor operations with those from xs_Float.h
* Replace multiple Q16.16 conversions from 0 to just be 0.
* Replaced all found in-game bit-shifts and multiplications/divisions with inline functions from m_fixed.h
* Replaced many casts of FRACUNIT as double in SW's panel.cpp as it is converted to double by way of type promotion.
* Fixed missed precision fixes in SW's panel.cpp where some types weren't declared correctly.
* Replaced 100+ `Cos()/Sin() >> 16` operations for Blood with inline functions `CosScale16()/SinScale16()`.
In particular this means to remove the option to disable widescreen aspect ratios. The way this was handled makes no sense with the current render backend.
The aspect ratio code will have to be redone entirely to properly obey the backend's settings.
* Changes performed in 0bd460d9e3 didn't take into account xdimenscale and viewingrangerecip like the days of old and this wasn't picked up in d80a32d379 or d80a32d379, where the applied fixes only appeared to work because they worked for me at 2560x1440p.
Models are currently non-functional and need to reroute their texture handling to the global texture manager instead of handling everything themselves.
Voxels also need a bit of work to make their texture management more automated.
This needs to be moved into the backend, and partially into the shader. So far this only removes the code from the main rendering logic, the final implementation is not done yet.
It had to go because it required the main rendering code to look deep into the texture data which would be a major blocker for refactoring.
- also removed the legacy fog modes because their implementation did not mix well with the texture system - they are also not really useful to begin with.
The last fog mode will most likely also be removed once true color shading is working but that one is less of an issue.
The EDuke32 and RedNukem frontends are working, Blood isn't yet.
Notes:
many of the CMake variables and its output still refer to zdoom. Before changing that I wanted to make sure to be able to commit something that works.
support code for Windows XP has been entirely removed. On Windows this will only target Vista and up.
the crc32.h header had to be renamed to deconflict from zlib.
several Windows API calls were changed to call the A-versions directly. Weirdly enough there were places that defined their parameters as T types but in a non-working way.
removed some remaining editor files and support for the native software rendering only Windows backend.
in a few simple cases, replaced 'char' with 'uint8_t'. The code as-is depends on chars being unsigned which is non-portable. This needs to be carefully reviewed.
Additionally, raise minimum number of stencil buffer bits to accomodate future use of the stencil buffer.

Use polymost_spriteHasTranslucency() and polymost_maskWallHasTranslucency() to determine if a sprite has translucency.
Optimize sprite rendering when in Polymost by only sorting sprites with translucency.

This also locks the texture filtering options in the menu behind ifdef guards until they're fixed.
